greyhound
n. countablen. a tall, thin dog with long legs that can run very fast. People often use them for racing or hunting.
n. a slender, long-legged breed of dog characterized by its deep chest and aerodynamic build. Known for exceptional speed, it is traditionally utilized in coursing and commercial racing.
The greyhound ran across the field with incredible speed.
Many retired greyhounds are adopted as pets because they are surprisingly calm and quiet indoors despite their athletic history.
The sleek silhouette of the greyhound has been a symbol of nobility and speed in art and literature since the time of the ancient Egyptians.
From Old English grīġhund, from a cognate or borrowing of Old Norse grøy (“bitch”) (whence Icelandic grey, thus not related to the colour grey) plus hund (“hound”). Altered by folk etymology to appear to be grey + hound.
Commonly used as a modifier in 'greyhound racing' or as a proper noun for the American bus company.
