O.E. ænig "any, anyone," lit. "one-y," from P.Gmc. *ainagas (cf. O.S. enig, O.N. einigr, O.Fris. enich, Du. enig, Ger. einig). The -y may have dim. force here. Emphatic form any old ______ (British variant: any bloody ______) is recorded from 1896. At any rate is recorded from 1847. Among the large family of compounds beginning with any- , anykyn "any kind" (c.1300) did not survive. Anywhen (1831) is rarely used, but OED calls it "common in Southern [British] dialects."
