From Middle English odde, od 'odd (not even); leftover after division into pairs', from Old Norse oddi 'odd, third or additional number; triangle', lit. 'point of land, angle' (odda-maðr 'third man, odd man who gives the casting vote', odda-tala 'odd number') from oddr 'point of a weapon', from Proto-Germanic *uzdaz 'point'. Cognate to Icelandic oddi 'triangle, point of land, odd number', Swedish udda 'odd', udd 'a point', Danish od 'point of weapon' and odde 'a headland, point', Norwegian Bokmål odde 'a point', 'odd', 'peculiar'; related to Old English ord 'a point'

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').
