c. 1200, perhaps late Old English, kinraden, "family, lineage; race, nation, tribe, people; kinsfolk, blood relations," compound of kin (q.v.) + -rede (see -red). With unetymological first -d- (17c.) probably for phonetic reasons (compare sound (n.1)) but perhaps encouraged by kind (n.). As an adjective, 1520s, from the noun.
