- kind (n.)
- "class, sort, variety," from O.E. gecynd "kind, nature, race," related to cynn "family" (see kin), from P.Gmc. *gakundiz (see kind (adj.)). Ælfric's rendition of "the Book of Genesis" into O.E. came out gecyndboc. The prefix disappeared 1150-1250. No exact cognates beyond English, but it corresponds to adj. endings such as Goth -kunds, O.H.G. -kund. Also as a suffix (mankind, etc.). 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 adv. (1804) in phrases such as kind of stupid ("a kind of stupid (person)").
- kind (adj.)
- "friendly," from O.E. gecynde "natural, native, innate," originally "with the feeling of relatives for each other," from P.Gmc. *gakundiz, from *kunjan (see kin), with collective prefix *ga- and abstract suffix *-iz. Sense development from "with natural feelings," to "well-disposed" (c.1300), "benign, compassionate" (c.1300). Kindly (adj.) is O.E. gecyndelic. Kind-hearted is from 1530s; kindness is from late 13c.
