He became more garrulous after drinking a couple of beers.
<a garrulous boy who was in constant trouble for talking out of turn>
Salman grew ever more garrulous as the yellow liquid in the bottle went down; Baal couldn't recall when he'd last heard anyone talk up such a storm. —Salman Rushdie, The Satanic Verses,1989
To an American reader in 1982, confronted with this garrulous, indefatigably quirky, I'm-just-typing-on-yellow-paper-and-associating-ideas-and-memories prose work of l936, such a judgment, by a presumably informed person, seems preposterous. —Joyce Carol Oates, New York Times Book Review,3 Oct. 1982
He was not garrulous by any means. On the contrary, there was a fine reserve in his manner toward the entire domestic economy of his life which was all that is comprehended by the popular term, gentlemanly. —Theodore Dreiser, Sister Carrie,1900
