means A large, powerful spotted wild cat native to the Americas, the biggest cat of the New World and an apex predator.

from From the Tupi-Guaraní languages of South America, where the word was something like 'yaguara' — often glossed as a beast that overpowers its prey in a single bound. Portuguese colonists picked it up as 'jaguar,' and from there it spread into the wider European tongues, carrying its native sense of a hunter that takes you in one leap.
