c. 1200, perhaps late Old English, kinraden, "family, lineage; race, nation, tribe, people; kinsfolk, blood relations," compound of kin (q.v.) + -rede, from Old English ræden "condition, rule," related to rædan "to advise, rule" (from PIE root *re- "to reason, count"). With unetymological -d- (17c.) probably for phonetic reasons (compare sound (n.1)) but perhaps encouraged by kind (n.). As an adjective, 1520s, from the noun.
