Word Origin & History

L. adv. and prep. meaning "down from, off, concerning," from PIE demonstrative stem *de-.

active prefix in English and in many words inherited from Fr. and Latin, from L. de "down, down from, from, off, concerning," also used as a prefix in Latin usually meaning "down, off, away, from among, down from," but also "down to the bottom, totally" hence "completely" (intensive
or completive), which is its sense in many English words. As a Latin prefix it also had the function of undoing or reversing a verb's action, and hence it came to be used as a pure privative -- "not" -- which is its primary function as a living prefix in English, as in defrost (1895), defuse (1943), etc. Cf. also dis-.
