Etymology

It is inherited from Middle English losen (“to be lost, perish”),[2][3] inherited from Old English losian (“to be lost, perish”),[4][2] from los (“destruction, loss”),[4][3][5] from Proto-Germanic *lausa-, the source also of loss, loose and -less.[4] It is from Proto-Indo-European *leu- (“to loosen, divide, cut apart”),[4][3] through an extended form *leus-,[4] and Latin luere (“to atone for”) and Greek λύειν (lúein, “to loosen”) are cognates.[6][2] It merged with the related Middle English leese, from Old English lēosan (“to lose”),[4][5] whose past participle loren survives in forlorn.[4] The pronunciation with /uː/ was probably influenced by loose.[5][6]

Earliest recorded meaning

“To perish, be lost”: before 725 in Barnhart,[2] or about 888 in the OED.[7] Barnhart dates Middle English losen “to be lost” to 1120, in the Peterborough Chronicle.[2]

Semantic evolution

The transitive senses came from the merger with leese:[4] “to be deprived of, part with accidentally”, of money, blood or sleep, is from about 1200,[4][7] and the loss of a relative by death also from about 1205.[7] “To fail to keep track of” is from the mid-13th century,[4] and “to fail to win” something from about 1300, intransitive “to be defeated” from the late 14th century.[4] “To fail to maintain”, as in lose patience, is from the mid-15th century[4] or 1436.[7] “To cause someone to lose his way” is from the 1640s, and “to get rid of” something unwanted from the 1660s.[4] A clock loses time when it runs slow.[8]

Usage notes

The SOED records two unrelated obsolete words: a noun lose, “praise, fame”, from Old French los, from Latin laudēs, used from Middle English to the early 19th century, and a verb “to praise” from it.[5][7] A slang noun lose, a lost race, is from 1884.[7][5]
