Rapid or indistinct talking; the act or instance of gabbling.
From 'gabble' plus the suffix '-ment,' which comes from Old French and Latin and creates nouns describing actions or states. This is a relatively rare formation in English.
Gabblement is an archaic-sounding word that captures exactly what happens when someone's words tumble out too fast to follow—it's the noun version of the chaotic act itself.
