The act of brabbling; a noisy argument or quarrel over trivial matters; the state of confusion resulting from pointless disputes.
From brabble plus the noun suffix -ment, which converts verbs into nouns describing actions or states. This creates an abstract noun for the activity and result of brabbling.
Medieval and Renaissance writers loved 'brabblement' as a word for the kind of chaos that erupts when multiple people argue about nothing—it perfectly captures noisy confusion without any real substance.
