IPA: /ˈsnɑːrlər/
KK: /snɑr.lɚ/
A person who often shows anger or hostility, often by growling or making a harsh sound.
The snarler at the party made everyone feel uncomfortable with his constant complaints.
Snarler → The word is formed from "snarl" (of uncertain origin, possibly imitative of the sound made) and "-er" (meaning a person who). A snarler is a person or animal that snarls, producing a growling or threatening sound.
Think of someone who makes a growling sound — that's what a snarler does, as the word comes from the sound itself.
