IPA: /ˈpaʊnsər/
KK: /ˈpaʊnsər/
A person or animal that jumps or leaps onto something, often to catch or surprise it.
The cat is a skilled pouncer, always ready to leap at its toy.
Pouncer is formed from "pounce" (from Middle English *pouncen*, meaning to leap or spring) and the suffix "-er" (meaning a person who). The word "pouncer" refers to a person or animal that leaps or springs at something, typically to catch it.
Think of someone who 'leaps' ('pounce') to catch something — that's why a 'pouncer' is someone who jumps to grab.
