Synonyms-denote the concept in an identical way they can substitude each other in any. One of two or more words (commonly words of the same language) which are equivalents of each other; one of two or more words which have very nearly the same signification, and therefore may often be used interchangeably.
There are many types of synonyms:stylistic,absolute,ideographic,contextual,pair,phraseological.Synonyms are different words with identical or at least similar meanings. Words that are synonyms are said to be synonymous, and the state of being a synonym is called synonymy. An example of synonyms are the words car and automobile, or announcement and declaration.
Let me give some more examples of synonyms:shake-trembling-shivering,like-love-adore,dislike-hate-loath,visage-mag,child-infant-kid.Synonyms can be nouns, verbs, adverbs or adjectives, but both words must be of the same part of speech.
That means, only a noun can be a synonym of another noun, only a verb can be a synonym of another verb, and so on.All languages tend to clear themselves of synonyms as intellectual culture advances, the superfluous words being taken up and appropriated by new shades and combinations of thought evolved in the progress of society.
