ordure

From Middle English ordure, ordure, borrowed from Middle French ordure and Anglo-Norman ordure, ordeur(e), ordor(e), ordour from Old French ordure (“dirt, filth, refuse; dung, excrement; moral filth”) (modern French ordure), from ord (“filthy”) + -ure (suffix forming nouns describing the results of actions). Ord is derived from Latin horridus (“dreadful, frightful, horrid”), from horreō (“to stand erect, stand on end; to shiver, tremble; to be afraid of, dread; to be frightful”) (ultimately from Proto-Indo-European *ǵʰers- (“stiff; surprised”)) + -idus (suffix meaning ‘tending to’).
