annoy: [13] Annoy comes ultimately from the Latin phrase in odiō, literally ‘in hatred’, hence ‘odious’ (odiō was the ablative sense of odium, from which English got odious [14] and odium [17]). The phrase was turned into a verb in later Latin – inodiāre ‘make loathsome’ – which transferred to Old French as anuier or anoier (in modern French this has become ennuyer, whose noun ennui was borrowed into English in the mid 18th century in the sense ‘boredom’). => ennui, noisome, odious
