kith [Old English] Old English cȳthth, of Germanic origin, is related to couth. The original senses were ‘knowledge’, ‘one’s native land’, and ‘friends and neighbors’. The phrase kith and kin originally referred to a person’s country and relatives, later coming to specify one’s friends and relatives.
