the.com/jabber

means To talk rapidly and indistinctly, often excitedly or nervously, with the words tumbling out faster than they can be properly shaped.

from Likely imitative in origin — one of those words that tries to sound like the thing it describes, the quick 'jab-jab-jab' of hurried syllables. It emerged in English in the 1500s alongside cousins like 'gibber' and 'gabble,' part of a whole family of nonsense-adjacent words born from mimicking chatter rather than tracing to any single root. Lewis Carroll later borrowed its sound for 'Jabberwocky,' cementing its association with speech that's energetic, tumbling, and not entirely making sense.
