Word Origin & History
also dependent, early 15c. (adj.); of persons, from 1580s, from Fr. dépendant (adj. and noun), properly prp. of dépendre "to hang down," also "to depend," from L. dependentem (see depend
). As with its relative dependence
Latin-influenced variant (in this case dependent) co-existed through 18c., but with this word the French spelling has proven more durable in English, possibly because it has been found convenient to keep both, one (dependant) for the noun, the other (dependent) for the adjective.
