SYNONYM. A WORD that means the same as another, such as male and masculine. Linguists and many writers agree that there is ‘no such thing as a synonym’, though the reasons for their opinions may differ. Linguists maintain that no two words have the same distribution, frequency, connotation, or language level; the reasons given by others are often vague, but in essence focus on differences in connotation, or reactions evoked in the reader or hearer by alternative words for the same thing. It is therefore perhaps best to say that a synonym is a word that shares the same denotation with another word. Notwithstanding disputes over the validity of the concept, there is a substantial body of published information containing synonym lists and studies, and it has become standard practice among dictionary publishers to include some of that information in general dictionaries. See ANTONYM, BISOCIATION, BOOK OF COMMON PRAYER, SEMANTICS, SYNONYMY, THESAURUS.
