loquacious means talkative; chatty.
loquacious is pronounced /ləʊˈkweɪʃəs/.
Why “loquacious” is a great word
Given to excessive or fluent talk; talkative. From Latin loquāx, loquācis ('talkative'), from loquī ('to speak') + the English suffix -ous. Unlike 'garrulous,' which implies rambling or tedious chatter, or 'taciturn,' its reserved antithesis, loquacious can cloak a certain articulate fluency within its verbosity. It is the unceasing patter of a summer downpour on a tin roof, the cab driver who narrates the city's hidden history through the rearview mirror, the intricate, self-sustaining circuitry of a thought finding its every possible expression—a celebration of sound that can, in its purest form, become a kind of lonely music, filling the air simply to prove the speaker still exists.
