English Synonyms and Antonyms
Vain (Latin vanus, empty) keeps the etymological idea through all changes of meaning; a vain endeavor is empty of result, or of adequate power to produce a result, a vain pretension is empty or destitute of support, a vain person has a conceit that is empty or destitute of adequate cause or reason. That which is bootless, fruitless, or profitless fails to accomplish any valuable result; that which is abortive, ineffectual, or unavailing fails to accomplish a result that it was, or was supposed to be, adapted to accomplish. That which is useless, futile, or vain is inherently incapable of accomplishing a specified result. Useless, in the widest sense, signifies not of use for any valuable purpose, and is thus closely similar to valueless and worthless. Fruitless is more final than ineffectual, as applying to the sum or harvest of endeavor. That which is useless lacks actual fitness for a purpose; that which is vain lacks imaginable fitness. Compare VACANT; OSTENTATION; PRIDE.
