In its narrowest sense, a synonym is a word or phrase that is perfectly
substitutable in a context for another word or phrase. People who study
language professionally agree that there is no such thing as an ideal
synonym, for it is virtually impossible to find two words or phrases that
are identical in denotation (meaning), connotation, frequency,
familiarity, and appropriateness. Indeed, linguists have long noted the
economy of language, which suggests that no language permits a perfect
fit, in all respects, between any two words or phrases.
