To gabble means to talk rapidly and excitedly in a way that's hard to understand, like when words tumble out so fast they blur together. Picture a group of friends all trying to tell the same exciting story at once, their words overlapping and running together: “And then he said and I was like and we saw and it was so”. That's gabbling.

The word often suggests nervousness or excitement that makes someone speak too quickly. A student called on unexpectedly might gabble through an answer, racing through it so fast that the teacher has to ask them to slow down and repeat it. Geese and turkeys are said to gabble because of their rapid, chattering sounds.

Gabble can also be a noun describing the sound itself: the gabble of voices in a crowded cafeteria or the gabble of excited kids describing their field trip all at the same time. When someone gabbles, they're usually so caught up in what they're saying that they forget to make sure anyone can actually understand them.
