Idioms and Phrasal Verbs

Origin of loss

  • Middle English los from Old English lose

    From American Heritage Dictionary of the English Language, 5th Edition

  • Old English has los "loss, destruction," from a Proto-Germanic root *lausam- (see lose), but the modern word probably evolved in the 14th century from lost, the original past participle of lose, itself from Old English losian "be lost, perish," from los "destruction, loss", from a Proto-Germanic root *lausa (compare O.N. los "the breaking up of an army"), from Proto-Indo-Eeuopean base *leu- "to loosen, divide, cut apart, untie, separate"
