means A dog of breeds like the greyhound or whippet that hunts primarily by sight and raw speed rather than by following scent.

from A straightforward compound: 'sight' plus 'hound' (from Old English hund, meaning simply 'dog'). It was coined to distinguish these breeds from 'scent hounds' like bloodhounds, which track prey by nose over long distances. Sighthounds instead rely on keen eyesight to spot movement at a distance, then close the gap with a short, explosive burst of speed — a hunting style ancient enough to appear in artwork from early Egyptian and Middle Eastern civilizations, though the English term itself is a modern classificatory label rather than an old folk word.
