means A short, casual term for an alligator — a large, armored reptile that lurks in swamps and rivers.

from Simply a clipped, informal shortening of 'alligator,' which itself traces back to Spanish 'el lagarto' — 'the lizard' — a name English-speaking explorers picked up in the Americas and mangled into English. 'Gator' is the lazy, friendly nickname that stuck once the word had worn comfortable in everyday speech.
