- loß (obsolete)
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"
