IPA: /ˈkætəˌmaʊnt/
KK: /kætəˌmaʊnt/
A wild cat, especially a mountain lion or similar large feline.
The catamount prowled silently through the forest, searching for its next meal.
Catamount is formed from "cata-" (from Latin *cattus*, meaning cat) and "mount" (from Old French *mont*, meaning mountain). The word refers to a wild cat that inhabits mountainous regions.
Think of a 'cat' ('cata-') that lives in the 'mountains' ('mount') — that's why a catamount is a wild cat found in mountainous areas.
