Word Origin & History

spin
O.E. spinnan "draw out and twist fibers into thread," from P.Gmc. *spenwanan (cf. O.N., O.Fris. spinna, Dan. spinde, Du. spinnen, O.H.G. spinnan, Ger. spinnen, Goth. spinnan), from PIE *(s)pen- "stretch" (cf. Armenian henum "I weave," Gk. patos "garment, lit. "that which is spun," Lith. pinu "I plait,
braid," spandau "I spin," M.Welsh cy-ffiniden "spider;" see span (v.)). Sense of "to cause to turn rapidly" is from 1612; meaning "revolve, turn around rapidly" first recorded 1667. The noun meaning "fairly rapid ride" is from 1856. Meaning "attempt to influence reporters' minds after an event has taken place but before they have written about it" seems to have risen to popularity in the 1984 U.S. presidential campaign; e.g. spin doctor, first attested 1984. Spinning wheel is attested from 1404; spinning-jenny is from 1783 (see jenny); invented by James Hargreaves c.1764-7, patented 1770. Slang spin off (v.) is from 1957, from the noun phrase, which is first attested 1951, in a corporate sense.
