Tantivy is an adverb as well as a noun that refers to a rapid gallop. Although its precise origin isn't known, one theory has it that tantivy represents the sound of a galloping horse’s hooves. The noun does double duty as a word meaning "the blare of a trumpet or horn." This is probably due to confusion with tantara, a word for the sound of a trumpet that came about as an imitation of that sound. Both tantivy and tantara were used during foxhunts; in the heat of the chase, people may have jumbled the two.
