The state of being annoyed or irritated; something that causes annoyance.
From annoy (from Old French anoier, meaning 'to harm or injure') + -ment (suffix forming nouns of action or state). The -ment suffix evolved in English to denote the result or product of an action.
While 'annoyment' isn't common in modern English—we usually say 'annoyance'—it reveals how English speakers constantly experiment with word-building, adding suffixes to create new emotional descriptions.
