Yawp
jɔːp
noun; verb
A loud, rough cry or shout. As a verb, to yawp is to cry out noisily.
Both book examples below use the noun. In Whitman's phrase 'my barbaric yawp', 'my' identifies the cry as something he sounds, not an action expressed by the word itself.
See how Walt Whitman and James Joyce use "yawp", with its meaning, pronunciation and real book examples.
