The act of cursing; a curse or execration; an archaic or obsolete term for cursing or something that is cursed.
From 'curse' plus the suffix '-ment,' which creates nouns from verbs (like 'treat' → 'treatment'). This medieval formation is rarely used in modern English, having been largely replaced by 'curse' or 'cursing.'
Medieval English loved '-ment' endings (payment, judgment, amazement), but 'cursement' never really caught on—we just use the noun 'curse' instead, showing how not all grammatically possible words survive in actual use.
