Synonym

synonym is a word that means exactly the same as, or very nearly the same as, another word in the same language. For example, "close" is a synonym of "shut".

Note that a synonym may share an identical meaning with another word, but the two words are not necessarily interchangeable . For example, "blow up" and "explode" have the same meaning, but "blow up" is informal (used more in speech) and "explode" is more formal (used more in writing and careful speech).
