Word Origin & History
loath
O.E. lað "hostile, repulsive," from P.Gmc. *laithaz (cf. O.Fris. leed, O.N. leiðr "hateful, hostile, loathed," M.Du. lelijc, Du. leelijk "ugly," O.H.G. leid "sorrowful, hateful, offensive, grievous," Ger. Leid "sorrow," Fr. laid "ugly," from Frank. *laid). Weakened meaning "averse, disinclined" is attested from c.1374. Loath to depart, a line from some long-forgotten song, is recorded since 1584 as a generic term expressive of any tune played at farewells, the sailing of a ship, etc.
