Plural of greyhound; sleek, fast dogs with long legs and narrow heads, originally bred for chasing game like hares and deer.
From Old English 'greghund,' where 'greg' meant 'dog' (related to Greek 'gryps'); the first part may also relate to 'Greek,' though this is debated; widely used since medieval times.
Greyhounds have been prized for 2,000+ years—ancient Egyptians, Greeks, and Romans all treasured them for hunting—and they're so aerodynamic that they became the symbol for speed itself!
