​FIEF, a feudal estate in land, land held from a superior (see Feudalism). The word is the French form, which is represented in Medieval Latin as feudum or feodum, and in English as “fee” or “feu” (see Fee). The A. Fr. feoffer, to invest with a fief or fee, has given the English law terms “feoffee” and “feoffment” (q.v.).
