"class, sort, variety," from Old English gecynd "kind, nature, race," related to cynn "family" (see kin), from Proto-Germanic *gakundjaz "family, race" (see kind (adj.)).

Other earlier, now obsolete, senses in English included "character, quality derived from birth" and "manner or way natural or proper to anyone." Use in phrase a kind of (1590s) led to colloquial extension as adverb (1804) in phrases such as kind of stupid ("a kind of stupid (person)").
