The act or process of discussing; a discussion or debate.
From discuss + -ment (a suffix forming nouns from verbs, denoting an action or result). This follows the pattern of settlement, agreement, and amusement, though it's quite archaic.
'Discussment' is one of those perfectly logical English words that simply never caught on—we prefer 'discussion' for the outcome and 'discussing' for the action, leaving discussment as a ghostly alternative.
