Synonym

Part of speech: noun (n.)

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. See under Synonymous. [Written also synonyme.] 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. De Quincey. His name has thus become, throughout all civilized countries, a synonym for probity and philanthropy. Macaulay. In popular literary acceptation, and as employed in special dictionaries of such words, synonyms are words sufficiently alike in general signification to be liable to be confounded, but yet so different in special definition as to require to be distinguished. G. P. Marsh.
