Some Background Synonyms are different words (or sometimes phrases) with identical or very similar meanings. Words that are synonyms are said to be synonymous, and the state of being a synonym is called synonymy. The word comes from Ancient Greek syn ("with") and onoma ("name"). The words car and automobile are synonyms. Similarly, if we talk about a long time or an extended time, long and extended become synonyms. In the figurative sense, two words are often said to be synonymous if they have the same connotation.

Remember that many thousands of English words that are spelled the same have very divergent meanings.
