Abstract

The research is a lexico-semantic analysis of the inaugural speech of president Asiwaju Bola Ahmed Tinibu. A simple random sampling technique was adopted for the studyand Componential Analysis in order to look at the features of every lexeme in analyzing the speech. The researchers hinged the study on Jose Trier’sLexical Field Theory and SemanticField(1931) as it theoretical model. The result shows that the semantic features employed in the speech significantly impact its effectiveness and persuasive power. They help to shape the audience's perception, evoke specific emotional responses, establish credibility, and enhance the persuasive impact of the speech. Thelexico-semantic features employed in the speech are proficiently and manipulatively used to shape the audience's perception and generate a specific response. They range from positive and impactful language to emotive language, expert vocabulary, and figurative expressions. By carefully choosing words and crafting these linguistic features. The speech aims to appeal to the audience's emotions, establish credibility, and persuade them to support the speaker's vision and goals.

1.0 Introduction

Semantics deal with meaning. At the lexico-semantic level, one looks at the lexical choices made by a writer or speaker. Here, words can be chosen for their denotative, connotative and other dimensions of meanings. Look at this line: “But tomorrow cannot be consoled.” The above line is taken from Yeibo’sMaiden Lines. Syntactically, i.e., in terms of grammar, the line is normal. The sentence begins with ‘but’, giving the assumption that it contrasts with the idea that precedes it. But if one looks at the sentence semantically, “tomorrow” is not an animate thing that can be consoled; it is only humans that can be “consoled” or not consoled. Making “tomorrow” to go with “consoled” creates some effect at this level.

Basically, Lexico-Semantic level is the study of the meaning of words either connotative or denotative such as diction, choice of words and figures of speech. In this context, Leech (150) and Lyons (155), studied the meaning of words, phrases, sentences and their diverse types differentiating conceptual, connotative, emotive and other meanings. For Leech, there are different types of meaning as associative and conceptual meaning. This type of meaning is related to the dictionary definition of a word, or the exact meaning. Leech defines conceptual meaning as “the widely assumed to be the central factor in linguistic communication…” Leech (150).

The inaugural speech of Asiwaju Bola Ahmed Tinubu is expected to show his personal political ideologies and his views of building a better Nigeria both now and the future perspective. By also examining the rhetorical strategies employed by the speaker, the effect that persuasion and manipulation can have on the audience will also be shown. Unequivocally, this study is based on questions such as: “what are the kinds of strategies employed by these political intellects to sway their audience and engage in power struggle; how are power and identity displayed through the use of emotive lexis and syntax, and personal deixis; and how are political ideologies constructed, articulated and redefined by linguistic resources; and what is the nature of the procedural frameworks that vividly show the sociolinguistic generalisations of arrangement and uniqueness in relations to their linguistic forms?” To answer the question above, the researcher intends to study the Lexico-semantic analysis of the inaugural speech of president Bola Ahmed Tinubu to justify the relationship between the lexical items and what they signified.

1.1 Empirical Study

There are many studies conducted by different exponents on the lexico-Semantic analysis of political speeches. Ayeomoni, (204) stated that politicians have a systemic and coherent way of using language to convey their political views. That “in some contexts, politicians may resort to using figurative or metaphorical language. They adopt this style when they intend to convey their intentions or message convincingly so that the impression being given could be printed and lasting in the minds of their listeners. It is also a language strategy used to arouse the feelings and collective excitement and sentiments of their followers and also to sustain their support and fellowship”. In elucidating on the concepts ‘language and politics’, Awonuga (188) stated that one aspect of Chief ObafemiAwolowo’s speech which one notices fairly quickly when reading his writings is the use of language which he makes of legal terms and expressions; and that ‘coupling’ is another feature of Awolowo’s language. To him, “coupling is the practice of using two words linked by the conjunctive word ‘and’ in places where one word would have been adequate”.

In explaining the way creative resources of language are employed in political speaking, Oyeleke (204) said that “ancient rhetoricians used to distinguish between three stages in rhetoric. The first was known as the ‘inventio’ (which is the finding or discovery), the second was the ‘dispositio’ (which is the arranging, structuring, or plotting), and the third was the ‘elocutio’ (which is the style). The first stage is known to everybody because everyone has some message or information to pass across before speaking. Once we have this message, the next stage is to decide on how to arrange, structure or plot this message which we want to pass across. And after this we can then choose the style in which to present the information”.

In a study conducted to analyse the language that the political elite use while discussing and conducting the business of politics, Ayeomoni (204) also concluded that “it is obvious from the analyses of the political speeches that the language of the political elite in Nigeria is more often than not exhibiting some unique features which renders it a variety of language”.

vanDijk (198) clarified the notion of political discourse. According to him, “first of all, political discourse will be primarily about politics, again as defined above. That is, we may typically expect overall meanings related to political systems, ideologies, institutions, the political process, political actors, and political events. In other words, much political discourse is reflexive. This is not quite trivial, because this reflexivity is not typical for educational, scholarly, or legal discourse. Thus, campaigning politicians will speak about themselves as candidates, about the elections, about voting for them, and the policies they promise to support when elected. They speak about opponents and political enemies and about the bad politics and policies of previous presidents, governments or parliaments, for dissidents and those who challenge political power.

More officially, governments or parliaments also refer to their own policies and political actions in decision making discourse”. Larswell (165) concluded with this statement, “like in magic too, the smallest portion of truth is interwoven with falsehood of every shade of plausibility made possible by the use of language”. This shows that messages are at times passed on in a manipulative and persuasive way, and may be intertwined with some modified truth or even total lies. Mazrui (175) in Bayode (210) stressed that “language is a vehicular expression of politics and a major tool in political behaviour”. We cannot, therefore, doubt the fact that language and politics are correlated.

According to Gastil (193), “politics and discourse are inextricably intertwined. Political interaction requires language structures, and linguistic behaviour necessarily involves structures of domination and legitimation. In this sense, all discourse is political; however, political discourse occurs when political actors, in and out of government, communicate about political matters, for political purposes”. Gastil (193) further stated that “political talk plays a vital role in shaping and transforming social reality, and as the interest of the world has recently turned toward democracy, discourse analysts might do well to make explicit the connections between their research and the pursuit of the democratic ideal.” Despite all the research conducted by many experts on the related topic, there is none on the inaugural speech of Mr. President at the eagle square. Hence the need for this study.

2.0 Research Methodology

A qualitative research method was adopted by the researcher where emphasis was placed on the speech. A simple random sampling method was adopted for the study. Therefore, qualitative method was used to describe the lexico-semantic variations gathered and to explain their psycho-sociolinguistic underpinnings. The data were collected through the secondary means where the researcher downloaded the speech from the Google play store before analyzing the data. The researcher used the lexical theory in the first phase of the analysis then, the semantic theory of Truth Conditional Semantic to ascertain the validity of the matters pointed out by the president. Finally,

3.0 Theoretical Framework

The research adopts the Jose Trier’s LexicalField Theory (1931) as it theoretical model. Lexical field refers to a group of semantically related words associated with a common area of meaning or experience. It plays a significant role in linguistics, discourse analysis, stylistics, and literary studies because it helps explain how vocabulary items function together to create meaning in communication. Through lexical field analysis, researchers can identify themes, ideologies, and patterns of language use in texts such as political speeches, literary works, and everyday communication.

This theory argued that words acquired their meaning through their relationships to other words within the same word-field. An extension of the sense of one word narrows the meaning of neighboring words, with the words in a field fitting neatly together like a mosaic. If a single word undergoes a semantic change, then the whole structure of the lexical field changes. The lexical field is often used in English to describe terms further with use of different words. Trier's theory assumes that lexical fields are easily definable closed sets, with no overlapping meanings or gaps.

The research is also germane with a Semantic Field (1931). Semantic Field Theory developed mainly in the early twentieth century through the works of linguists such as: Jost Trier, Leo Weisgerber, Ferdinand de Saussure. Jost Trier is often regarded as the major proponent of the theory. He argued that vocabulary is organized into interconnected systems where the meaning of one word depends on the meanings of related words within the same field. The theory was influenced by structural linguistics, particularly the ideas of Ferdinand de Saussure, who viewed language as a system of interrelated signs. A semantic field refers to a set of words related in meaning because they describe a particular area of experience or knowledge. These words may belong to the same grammatical category or different categories.

The theory holds that vocabulary items do not exist independently; rather, they function within networks of meaning called semantic fields or lexical fields. A semantic field consists of words that share a common conceptual domain. For example, words such as teacher, student, classroom, examination, and curriculum belong to the semantic field of education. The theory emphasizes that the meaning of a word can best be understood in relation to other words within the same field. Thus, language is viewed as a structured system in which words are interconnected semantically.

The Theory proposes that, a group of words with interrelated meanings can be categorized under a larger conceptual domain. This entire entity is thereby known as a semantic field. Semantic field theory does not have concrete guidelines that determine the extent of semantic relations between lexemes. The abstract validity of the theory is a subject of debate knowing the meaning of a lexical item therefore means knowing the semantic entailments the word brings with it. However, it is also possible to understand only one word of a semantic field without understanding the other related words. A semantic field can thus be very large or very small, depending on the level of contrast being made between lexical items. Is suitable for the topic under study since the researcher intends to critically study Lexico-Semantic analysis of the inaugural speech of president Asiwaju Bola Ahmed Tinubu on the 29th, May 2023 at the Eagle Square Abuja, Nigeria.

4.0 Data Presentation, Analysis and Discussion

Language is a powerful tool that allows individuals to express their thoughts, ideas, and emotions. The choices and patterns of words used, along with their underlying meanings, play a crucial role in shaping the impact and effectiveness of a text. Thus, analyzing the lexico-semantic features of a piece of writing becomes essential in understanding the intended message and the persuasive techniques employed. In this analysis, the researcher will examine the lexical and semantic aspects present in the inaugural speech of President Bola Ahmed Tinubu. Lexical choices refer to the specific words employed by the author or speaker, carrying unique connotations and serving to elicit certain emotions or ideas. Semantic patterns and themes, on the other hand, involve the underlying patterns and recurring motifs that shape the overall meaning and message conveyed in the text. This section presents the analysis of data collected for the study titled “Lexico-Semantic Analysis of President Bola Ahmed Tinubu’s Inaugural Speech on 29th May, 2023.” The analysis is carried out using the theoretical frameworks of Lexical Field Theory and Semantic Field Theory. The section focuses on the lexical choices, semantic relations, and communicative functions of language employed in the inaugural speech delivered by entity ("politician","Bola Ahmed Tinubu","President of Nigeria").Theresearch examines how lexical items are grouped into semantic and lexical fields in order to reveal the ideological orientation, thematic concerns, persuasive strategies, and communicative intentions embedded in the speech. Through lexical and semantic analysis, the researcher identifies the dominant vocabulary patterns used to express themes such as governance, democracy, economy, unity, security, development, hope, and national transformation.

4.1 Lexical Field analysis of the Speech

The major lexical fields identified in the speech include Governance and Democracy, Economy and Development, Unity and Nationhood, Security and Stability, Hope and Transformation, Labour and Employment and Patriotism and National Identity.

In Lexical Field of Governance and Democracy, the research reveals thatone of the dominant lexical fields in the speech is use of the lexeme governance and democracy. The president repeatedly uses words associated with political leadership, democratic governance, and constitutional administration.

“I am profoundly honoured to serve as your president.”

“Our constitution remains sacred.”

“Democracy has risen again in Nigeria.”

“We shall govern with fairness and justice.”

Lexical Field Theory is highly appropriate for the study titled “A Lexico-Semantic Analysis of President Bola Ahmed Tinubu’s Inaugural Speech” because the theory focuses on the relationship among words that belong to the same area of meaning. Since lexico-semantic analysis examines vocabulary choice and meaning in discourse, the theory provides a suitable framework for identifying and interpreting the lexical patterns used in the inaugural speech.

Political speeches are carefully constructed with selected lexical items aimed at persuading, informing, motivating, and influencing the audience. In an inaugural speech, the president uses language to communicate political ideology, national vision, government policies, and leadership intentions. Lexical Field Theory helps the researcher to group related words into lexical categories in order to reveal the thematic focus and communicative purpose of the speech. In the inaugural speech of Bola Ahmed Tinubu, several lexical fields can be identified. These lexical fields help to explain the dominant themes and ideological concerns expressed in the speech. For example, Words such as government , administration, democracy, leadership, constitution, governance, policy belong to the lexical field of governance. These lexical items reflect the speaker’s concern with political administration and democratic leadership.

He used Lexical Field of Economy byincludingWords like economy, investment, inflation, employment, industry, prosperity, and development toshow emphasis on economic growth and national development. The repeated use of these lexical items indicates the president’s intention to address economic challenges and improve citizens’ welfare. The speaker used some Lexical Field of Unity and Nationhood in the speech.Lexical items such asUnity, peace, togetherness, nation, citizens, cooperation, harmony demonstrate efforts to promote national integration and social cohesion among Nigerians.

Thereare Lexical Field of Security inWords like Security, safety, terrorism, violence, protection, stability whichreflect concerns about maintaining peace and protecting the nation from insecurity.And also there are Lexical Field of Hope and Progress through the expression ofWords such ashope, renewal, future, progress, transformation andgrowthtocreate optimism and inspire confidence in the new administration.

Lexical Field Theory is justified in this study because it enables the researcher to identify recurrent lexical items in the speech, classify words into semantic categories, examine the relationship among lexical choices, reveal the ideological orientation of the speaker, understand how language is used for persuasion and political mobilization and uncover dominant themes and communicative intentions in the speech. The theory also helps explain that meaning in political discourse is achieved not only through isolated words but through clusters of related vocabulary items. The repeated use of words within particular lexical fields reinforces specific political messages and shapes audience perception.

Furthermore, Lexical Field Theory is useful in discourse analysis because it reveals how politicians strategically select vocabulary to construct national identity, inspire hope, gain public trust, and legitimize authority. In Bola Ahmed Tinubu’s inaugural speech, the lexical choices project themes of democracy, economic reform, unity, and national development. In conclusion, Lexical Field Theory is suitable for the study because it provides a systematic framework for analyzing vocabulary and meaning relationships in Bola Ahmed Tinubu’s inaugural speech. The theory enables the researcher to identify lexical patterns, interpret thematic concerns, and understand the communicative and ideological functions of language in political discourse.

Semantic Field Analysis of the Speech

The research identifiedin the speech Democracy and Governance, Economy and Development, National Unity, Security and Peace, Hope and Renewal as Semantic field. This shows how words are connected through meaning relationships. In the inaugural speech, semantic fields help reveal thematic patterns and ideological structures. The major semantic fields in the speech includes:

Semantic Field of Democracy and Governance

The semantic field of democracy includes lexical items related to leadership, constitutional order, governance, and political legitimacy.The Semantic Items under this field includesdemocracy, constitution, government, administration, leadership, justice and authority.These semantic items collectively project democratic ideals and institutional governance. The semantic relationship among these words emphasizes constitutional authority and political stability. The field reflects the president’s attempt to legitimize his administration and reassure citizens of democratic continuity.

Semantic Field of Economy and Development

This semantic field includes words associated with economic activities and national advancement. The semantic items areeconomy, employment, development, prosperity, industry, investment and poverty reduction. The semantic field demonstrates the administration’s economic priorities. The interconnected meanings among these lexical items create the impression of a government focused on economic growth and citizens’ welfare.

Semantic Field of Unity and Nationhood

Some of the semantic items are unity, peace, togetherness, cooperation, nation, harmony and citizensThe semantic relationship among these words projects national integration and peaceful coexistence. The field seeks to encourage patriotism and collective responsibility.The research noted Semantic Field of Security and Peace in Items likesecurity, terrorism, violence, protection, safety, peace, andstability. This semantic field reflects concerns about insecurity in Nigeria. The words are semantically related through the concept of national safety and stability. The president uses these lexical items to assure citizens that the government will combat insecurity. Semantic Field of Hope and Renewal is also eminent in the speech.Itemslikehope, future, transformation, renewal, progress, changeandgrowth.This semantic field reinforces optimism and national aspiration. The repeated use of positive semantic items helps build confidence in the administration.

The significant linguistic features and semantic strategies inherent in the political speech

One of the significant linguistic features in this political speech is the use of historical references. The speaker invokes the idea of "founding fathers" who "gave bravely of themselves to place Nigeria on the map as an independent nation" over six decades ago. By referring to this historical event, the speech creates a sense of continuity and tradition, suggesting that the speaker's goals are aligned with the principles and aspirations of Nigeria's past leaders.

Additionally, the speech employs inclusive language to foster a sense of unity and national identity. The speaker consistently uses pronouns such as "we," "us," and "our" to include the audience in their vision and to emphasize that the proposed changes and goals are collective efforts. This linguistic strategy aims to build a connection between the speaker and the listeners, making them feel like an integral part of the progress and development of the nation. Semantic strategies in the speech include the use of rhetorical questions. For example, the speaker asks, "Let us take the next great step in the journey they began and believed in." By posing this question, the speaker engages the audience and prompts them to consider the importance of continuing the work started by previous generations. This strategy appeals to the audience's sense of duty and calls them to action, creating a persuasive effect.

The speech also employs contrasting statements to emphasize certain concepts. For instance, the speaker states that the Nigerian ideal is "more than just an improvement in economic and other statistics." By contrasting material progress with the broader ideals of compassion, fairness, and societal progress, the speech aims to transcend merely quantifiable outcomes and focus on the deeper values and principles that should guide the nation. The speech uses specific policy proposals in various areas, such as security, economy, jobs, agriculture, and infrastructure, to showcase the speaker's comprehensive approach to governance. This strategy allows the speaker to appeal to different segments of the audience by addressing their diverse needs and concerns. The speech ends with an emotional appeal and a call to action, emphasizing that the speaker's presidency will bring positive change and make the Nigerian ideal a reality.

The lexico-Samantic features and how they are proficiently and manipulatively used

In the speech, several lexico-semantic features were employed proficiently and manipulatively to shape the audience's perception and create persuasive effects. First, the use of positive and impactful language. The speaker employs words such as "great," "bravely," "proudly," "tremendous," and "remarkable" to emphasize the significance and success of Nigeria's past achievements. By using these expressive and enthusiastic terms, the speech aims to generate a positive emotional response from the audience and to instill a sense of pride and optimism.

Over six decades ago, our founding fathers gave bravely of themselves to place Nigeria on the map as an independent nation. We must never allow the labor of those who came before us to wither in vain but to blossom and bring forth a better reality.

Let us take the next great step in the journey they began and believed in. Today, let us recommit our very selves to placing Nigeria in our hearts as the indispensable home for each and every one of us regardless of creed, ethnicity, or place of birth.

My supporters, I thank you. To those who voted otherwise, I extend my hand across the political divide. I ask you to grasp it in national affinity and brotherhood. For me, political coloration has faded away. All I see are Nigerians. May we uphold these fitting and excellent notions as the new Nigerian ideal.

My fellow compatriots, The Nigerian ideal which I speak of is more than just an improvement in economic and other statistics. These things are important; but they can never convey the fullness of our story.

Secondly, thereare uses of emotive languagein the speech. The speaker employs words and phrases such as "struggles," "challenges," "hardships," and "desperation" to evoke empathy and create a sense of urgency. By using emotionally charged language, the speech seeks to elicit compassion from the audience and motivate them to support the proposed changes and goals outlined in the speech.

The speech also employs expert or technical language. The speaker uses terms such as "security architecture," "economic diversification," "job creation," and "agro-industrial processing zones" to demonstrate competence and expertise in various fields. By using specialized vocabulary, the speech aims to establish the speaker's credibility and convey the impression that they have a comprehensive understanding of the issues at hand.

Conclusively, the lexico-semantic features employed in the speech are proficiently and manipulatively used to shape the audience's perception and generate a specific response. They range from positive and impactful language to emotive language, expert vocabulary, and figurative expressions. By carefully choosing words and crafting these linguistic features, the speech aims to appeal to the audience's emotions, establish credibility, and persuade them to support the speaker's vision and goals.

The structure and the semantic roles; the consequence of these semantic features on the speech

The structure of the speech plays an essential role in organizing and presenting the speaker's ideas in a coherent and persuasive manner. Generally, a speech follows a standard structure that includes an introduction, body, and conclusion. In the introduction, the speaker typically grabs the audience's attention and outlines the main topic or purpose of the speech. The body of the speech contains the main points and supporting arguments, which are presented in a logical and structured manner. Finally, the conclusion summarizes the main points and provides a strong ending that leaves a lasting impression on the audience.

Semantic roles refer to the specific roles that words or phrases play in conveying meaning and relationships within a sentence or utterance. For example, in the speech, certain words or phrases may serve as subjects, objects, predicates, or modifiers, depending on their semantic roles. These roles help to clarify the grammatical structure and logical connections within the speech.

The consequence of the lexico-semantic features on the speech is to shape the audience's perception and influence their response or behavior. By using positive and impactful language, the speech aims to engender a sense of pride and optimism in the audience, contributing to a positive emotional response. The use of emotive language seeks to evoke empathy and urgency, motivating the audience to support the proposed changes and goals. The employment of expert vocabulary helps to establish the speaker's credibility and expertise, increasing the audience's trust and receptiveness to the ideas presented. Lastly, the use of figurative language and rhetorical devices enhances the persuasive effect of the speech. It engages the audience's imagination, making the ideas more vivid and memorable, and leaving a lasting impression on the audience. The semantic features employed in the speech significantly impact its effectiveness and persuasive power. They help to shape the audience's perception, evoke specific emotional responses, establish credibility, and enhance the persuasive impact of the speech.

The researchers selected some lexical items in order to look at the features of every lexeme in analyzing the speech. 

1. JOURNEY + vehicle + Animate -Inanimate + driver+ Passenger

2. PRAYERS + Human + God+ Religion+ perseverance +communication- disobedience+ answer

3. SACRIFICES+ obedience+ dedication+ perseverance+ prayer+ answer

4. HARDSHIPS + suffering+ sweating+ hunger+ starvation+ deprivation + Bad governance

5. CRUMBLE+ Fall+ stumble+ upset+ defeat+ disappointed+ loss of power

6. DEMOCRACY+ election+ voting+ government + representatives+ Masses

7. PEACEFUL TRANSITION+ handing over+ taking over+ new government

8. RESILIENCE + stubborn+ courage+ Depression+ misfortune

9. DIVERSITY + disunity+ differences+ multiplicity+ assortment + distinctiveness

10. CRITICS+ judgment + reviewer + interpreter + observer + scholiast

11. BREAK APART+ separate + disrupt + disunite + explode + rupture + dis-member

12. PERISH+ expire + wither + rot + vanish + molder + shrivel

13. Therefore presidents and leaders should adhere to these types of speeches without minding the writer’s status. Heed the advice given by others who can positively contribute to the act of governance. Also, National interest should surpass party interest so that the targeted development and plans would be achieved.

5.0 Discussion of findings

Because of the unfair nature of our electoral processes and of the gross imbalance of our political economy, the people have been props in a drama for which they should have been the main characters. We must change this. We must move Nigeria from the place where the whims and narrow wishes of self-centered reactionary elite dictate the fate of over 150 million people. Let Nigeria enter the place where the people take center stage and their elected leaders cease misbehaving like a modern-day aristocracy and get on with the task of national development in earnest.

First, we need to sanitize the electoral system. Material reform is needed. Unless reform comes, the next election will be abysmal and the people's will shall not prevail. And that would be dangerous. Let the next election be a fair and open contest between the PDP power and our progressive vision for change.

On our side, we will take our chances with a free and fair election. For we shall offer the people an innovative program, consisting of a national industrial policy that includes: radical infrastructural development and employment targets. It includes revival of agriculture through commodity exchange boards, education reform and of the modernization of essential social services including primary health care, especially for women and children to reduce maternal and infant mortality.

These and other people-oriented measures we pledge. We look forward to a public comparison of our plans to those of the past 14 years under the current government. This is what democracy is about. Let the people inspect each party's wares then vote for the package that suits them in an honest and transparent manner.

A truly free and fair election is what the Progressives ask for. One man, One vote. If we get this, we shall win because we seek to provide a new leadership that will lead Nigeria to a better place and future. A country where no responsible mother is forced to send her children to bed without food, where no son watches his mother pass away because he can't afford basic medical care and where every child can taste of a quality education that allows them to dream of being doctors, scientists, farmers, business people, nation builders, and even dream of being the president of our land. A Nigeria where everyday brain drains is converted to brain gain. This is the Nigeria we seek. This is the Nigeria that shall come to pass.

The current administration should apply a consistent policy of targeted law enforcement operations in conjunction with an active program of economic development, negotiations and potential amnesty for penitent Boko Haram members. Instead, the nation has been treated to series of government inaction, indiscriminate use of force, and now a state of emergency. The Jonathan government set up a special Committee on Boko Haram and Security matters but sadly before they could perform, he declared State of Emergency in three Northern states: Yobe, Borno and Adamawa. This is symptomatic of a confused leadership. If there is security in this jumbled policy, neither I nor the majority of Nigerians can find it!

On the State emergency declared, we told our National Assembly members to support it so long as it operates without affecting the democratic structure and without the federal government dipping its hands into the treasury of the States concerned. Before the end of the State of Emergency, we hope government will enumerate the number of victims including orphans, and the number of churches, mosques and properties of economic value destroyed. Government must them move to compensate the victims.

Semantic Field Theory is highly relevant and suitable for the study titled “A Lexico-Semantic Analysis of President Bola Ahmed Tinubu’s Inaugural Speech” because the theory provides an effective framework for examining how words are grouped according to meaning in a discourse. Since lexico-semantic analysis focuses on vocabulary choice and meaning relationships, Semantic Field Theory helps the researcher to identify and interpret the semantic categories embedded in the inaugural speech. An inaugural speech is a political discourse designed to communicate ideologies, policies, promises, national goals, and leadership intentions. Politicians carefully select lexical items to persuade, inspire, unite, and influence citizens. Through Semantic Field Theory, the researcher can classify these lexical items into semantic domains in order to reveal the thematic concerns and ideological focus of the speaker.

For instance, in Bola Ahmed Tinubu’s inaugural speech, words and expressions relating to unity, democracy, economy, development, security, hope, governance, and national progress can be grouped into different semantic fields. These lexical groupings help to explain the underlying meanings and communicative intentions of the speech. Semantic Field of Governance the researchers observedWords such as government, administration, leadership, democracy, constitution, policy reflect the speaker’s concern with governance and political administration.Looking at theSemantic Field of Economy, the researchers observedLexical items likeeconomy, investment, employment, inflation, prosperity development show emphasis on economic reforms and national growth. In Semantic Field of Unity and Nationhood, Words such as unity, togetherness, peace, nation, citizens, cooperationdemonstrate the speaker’s attempt to promote national integration and solidarity.More so, the Semantic Field ofSecuritywhere present in the speech.Words including security, safety, terrorism, violence and protection indicate concerns about national security and stability.

The theory is justified because it enables the researcher to identify dominant lexical patterns in the speech, examine relationships among words, interpret the ideological and political message of the speaker, reveal recurrent themes and communicative strategies, understand how language is used to persuade and mobilize the audience. Furthermore, Semantic Field Theory helps to explain how meaning in the speech is not conveyed by isolated words alone but through networks of related lexical items. This aligns directly with lexico-semantic analysis, which studies meaning relations among words in a text.The theory also assists in uncovering implicit meanings, emotional appeals, and rhetorical intentions in the speech. For example, repeated use of words associated with hope, renewal, and progress may project optimism and create public confidence in the new administration.In conclusion, Semantic Field Theory is appropriate for the study because it provides a systematic method for analyzing lexical choices and meaning relationships in Bola Ahmed Tinubu’s inaugural speech. The theory enables the researcher to classify vocabulary into semantic fields, interpret thematic structures, and reveal the ideological and communicative functions of language in political discourse.

6.0 Conclusion

This study is mainly concerned with lexicology and semantics as parts of the levels of language. These levels in turn were used in analyzing the data. The notion of word is central in the study of lexicology and semantics. Words and sentences are carefully selected and well-ordered to convey intentions. These words and sentences form themselves into coherent speech or text.
