 Effective language use is a basis for communication. Language is a system of symbols which includes words and words make up sentences that in turn form a discourse. Each word and sentence exhibit different form, nature, element and meaning. Thus, lexico – semantic level of language analysis deals with the study of word and meaning. This study examined the use of word and sentence, word group, meaning relations and cohesive devices in five selected speeches of Is-haq Oloyede, the Vice-Chancellor, University of Ilorin, as representatives of all his speeches in year 2010.These speeches contain more noun and more pronoun as word classes and different meaning relations that enhance grammatical senses. Also, the speeches exhibit some set of linking resources such as reference, ellipsis and substitution, conjunction and lexical cohesion. These resources create connection between words and sentences and between language and the world. Hence, the purpose of language use by Oloyede was achieved by the nature of a word, its group, element, the meaning it conveys and the relationship it shares with other words and sentences in his speeches.

Generally, it is accepted that language is the means by which people in a community interact and express feelings, thoughts and intentions. It is a system of voluntarily produced symbols which include signs, letters, words, etc. According to Udofot (2004,p.3) “language is normally organized into patterns-phonic and graphic and each has specific characteristics”. The purpose of language is for communication. Effective communication is based on a person’s linguistic ability to produce, pronounce and use words, ability to construct sentences and on the meaning of individual words and sentences. Hence, people communicate meaning with pieces of language. 
 There are different levels of language study, namely: morphology which is the study of word formation and structure; syntax which deals with the arrangement of words to form sentences; phonology which studies speech sounds and how they are organized into a system of a given language, etc. 
 This study will mainly concern itself with lexicology and semantics as parts of the levels of language. These levels will in turn be used in analyzing our data. The notion of word is central in the study of lexicology and semantics. Lexicology deals with the study of the form, meaning, use and behavior of words. Wikipedia, the free encyclopedia (2011) says “lexicology studies words, their nature and meaning, words elements, relations between words (semantic relations), word groups and the whole lexicon”. The term first occurred in the 1820s. Also, semantics deals with the study of meaning. It shows how words and sentences including non-verbal behaviours are understood, interpreted and related to objects and situations in the world. Semantics also relates syntactic structures to writing as a whole. 
Words and sentences are carefully selected and well-ordered to convey intentions. These words and sentences form themselves into coherent speech or text. A speech is defined as a connected discourse which is spoken formally to an audience. Speech by Hughes (1996,p.7) “ is primarily an aural or oral process which takes place through the dimension of time in a strictly linear fashion”. She describes a speech as a spoken channel of communication.
This work deals with the use of words, word groups and meaning relations that are internal to the vocabulary of English language using selected speeches of Is-haq Oloyede as case study. It will cover the theories of the classification and decomposition of word meaning and the relationship of word meaning and sentence meaning.
