Sometimes words come up in normal conversation. I heard someone say caterwaul recently. This is an older word that you do not hear much.
What does the noun caterwaul mean?
Basically, it means to protest or complain in a noise way. It can also be any harsh cry or a shrill howling/wailing sound.
Synonyms include but are not limited to: beef, bellyache, carp complain, grouse, grumble moan, squawk and whine.
