means A large tawny wildcat native to the Americas, also called a cougar, puma, or catamount, that preys on deer and roams one of the widest ranges of any land mammal in the Western Hemisphere.

from 'Mountain lion' is a plain 18th/19th-century English descriptor, not a borrowing — colonists simply named the big cat for where they met it and what it resembled. 'Cougar' and 'puma' trace to South America: puma comes from Quechua, while cougar traveled a twistier road through French, likely garbled from a Tupi word (via Portuguese 'çuçuarana') that got reshaped along the way. The animal's sheer number of regional names — painter, catamount, panther, ghost cat — reflects how widely it ranged and how many different peoples independently needed a word for it.
