Did You Know?
English has many terms for gabby types, but it's important to choose the right word to get across what kind of chatterbox you mean.
Talkative usually implies a readiness to engage in talk or a disposition to enjoy conversation.
Loquacious generally suggests the power to express oneself fluently, articulately, or glibly, but it can also mean "talking excessively."
Garrulous is even stronger in its suggestion of excessive talkativeness; it is most often used for tedious, rambling talkers.
Voluble is a word ultimately derived from the Latin verb volvere, meaning "to roll," that  describes an individual who speaks easily and often—someone whose words smoothly roll off their tongue, so to speak.
