adj.c.1300, “constituting a unit in excess of an even number,” from Old Norse oddi “third or additional number,” as in odda-maðr “third man, odd man (who gives the casting vote),” odda-tala “odd number.” The literal meaning of Old Norse oddi is “point of land, angle” (related via notion of “triangle” to oddr “point of a weapon”); from Proto-Germanic *uzdaz “pointed upward” (cf. Old English ord “point of a weapon, spear, source, beginning,” Old Frisian ord “point, place,” Dutch oord “place, region,” Old High German ort “point, angle,” German Ort “place”), from PIE *uzdho- (cf. Lithuanian us-nis “thistle”). None of the other languages, however, shows the Old Norse development from “point” to “third number.” Used from late 14c. to indicate a surplus over any given sum. Sense of “strange, peculiar” first attested 1580s from notion of “odd one out, unpaired one of three” (attested earlier, c.1400, as “singular” in a positive sense of “renowned, rare, choice”). Odd job (c.1770) is so called from notion of “not regular.” Odd lot “incomplete or random set” is from 1897. The international order of Odd Fellows began as local social clubs in England, late 18c., with Masonic-type trappings; formally organized 1813 in Manchester. abbr.
