One of the fundamental facts about words is that the most useful ones in our language have many meanings. That is partly why they are so useful: they work overtime... Think of –all the various things we mean by the word “foot” on different occasion: one of the lower extremities of the human body, a measure of verse, the ground about a tree, twelve inches, - the floor in front of the stairs. The same is true of nearly every common noun or verb... considering the number of ways of taking a particular word, the tusk of speaking clearly and being understood would seem pretty hopeless if it were not for another very important fact about language. Though a word may have many senses, these senses can be controlled, up to a point, by the context in which the word is used. When we find the word in a particular verbal setting - we can usually decide quite definitely which of the many senses of the word relevant. If a poet says his verse has feet, it doesn’t occur to you that he could mean it’s a yard long or is three legged (unless perhaps you are a critic planning to puncture the poet with a pun about his “lumping verse”). The context rules out these maverick senses quite decisively. The fundamental facts about word is that it had various uses in our languages.The word foot had different meanings on different occasions used as a part of human body or in measuring ratios.Word used as both noun or verb.Relevant word had many senses that can be understood by knowing the context in which they are used however verbal settings helped us to understand different senses of relevant words.
