Etymology

Sense 1: From Old English assa, from Latin asinus ("donkey"), possibly from a Semitic source. Senses 2-3: Originally from a different Old English word ærs ("buttocks"), which merged with the animal term in American English spelling. In British English, the vulgar term is typically spelled "arse."
