Word Nuance & Usage

While originally a standard livestock term for a male donkey, in modern usage 'jackass' is predominantly employed as a mildly vulgar, derogatory slang insult for a foolish or obnoxious person.

Word Origin & Etymology

First recorded in the early 18th century, formed by combining the masculine pet name 'Jack' (historically used to denote a male animal, as in 'jackdaw' or 'jackrabbit') with 'ass' (donkey), from Old English assa, ultimately derived from Latin asinus.
