Shades of meaning
Garrulous signifies given to constant trivial talking. Chattering signifies uttering rapid, noisy, and unintelligible, or scarcely intelligible, sounds, whether articulate words or such as resemble them; chattering is often used of vocal sounds that may be intelligible by themselves but are ill understood owing to confusion of many voices or other cause. The talkative person has a strong disposition to talk, with or without an abundance of words, or many ideas; the loquacious person has an abundant flow of language and much to say on any subject suggested; either may be lively and for a time entertaining; the garrulous person is tedious, repetitious, petty, and self-absorbed. Verbose is applied to utterances more formal than conversation, as to writings or public addresses. We speak of a chattering monkey or a chattering idiot, a talkative child, a talkative or loquacious woman, a garrulous old man, a verbose writer. Compare circumlocution.
