O.E.
wyrd "fate, destiny" (n.), lit. "that which comes," from P.Gmc.
*wurthis (cf. O.S.
wurd, O.H.G.
wurt "fate," O.N.
urðr "fate, one of the three Norns"), from PIE
*wert- "to turn, wind," (cf. Ger.
werden, O.E.
weorðan "to become"), from base
*wer- "to turn, bend" (see
versus). For sense development from "turning" to "becoming," cf. phrase
turn into "become." The modern sense of
weird developed from M.E. use of
weird sisters for the three fates or Norns (in Gmc. mythology), the goddesses who controlled human destiny. They were usually portrayed as odd or frightening in appearance, as in "Macbeth," which led to the adj. meaning "odd-looking, uncanny," first recorded 1815.
