The act or process of confirming; confirmation or the result of confirming something.
From 'confirm' plus the suffix '-ment' (expressing an action or result). The '-ment' suffix comes from Latin '-mentum' and Old French '-ment' and creates nouns from verbs.
English has multiple ways to nominalize the verb 'confirm': 'confirmation,' 'confirmity,' and 'confirmment'—but 'confirmation' completely dominates. This shows how languages eliminate redundancy over time, with one version winning out naturally.
