Word Origin & History
loaf (n.)
O.E. hlaf "bread, loaf," from P.Gmc. *khlaibuz (cf. O.N. hleifr, Swed. lev, Ger. Laib, Goth. hlaifs), of uncertain origin, perhaps connected to O.E. hlifian "to raise higher, tower," on the notion of the bread rising as it bakes, but it is unclear whether "loaf" or "bread" is the original sense. O.C.S. chlebu, Finn. leipä, Lith. klepas probably are Gmc. loan words. Meaning "chopped meat shaped like a bread loaf" is attested from 1787.
