Why this word is great
TANTIVY — [Adverb, Noun, Verb] At full gallop or speed; a rapid gallop or rush; to hurry off swiftly. Of uncertain origin, possibly imitative of the sound of a hunting horn or galloping horses. Unlike "gallop" (which describes a horse's gait) or "hasten" (which suggests mere acceleration), "tantivy" evokes the reckless abandon of pursuit—the thunder of hooves in a fox hunt, the blur of hedgerows as riders leap, the horn's cry sharpening the air. It is speed with a wild heart, the kind that leaves no room for second thoughts, only the mad, joyous certainty of forward motion.
