'annoyment' originates from Old French, specifically the word 'anoier' (also written 'anoier'/'anoir'), where the root 'odium' (via Romance/Vulgar Latin) meant 'hatred' or 'disgust'.

'annoyment' changed from Middle English forms (e.g. 'annoyen', 'annoyment') derived from Old French 'anoier' and eventually became the modern English noun 'annoyment' (now rare; more commonly 'annoyance').

Initially, related words meant 'to make hateful' or 'to cause disgust/torment'; over time the sense narrowed to the modern meaning 'to irritate or bother'.
