noun
greyhound
GRAY-hownd/ˈɡreɪhaʊnd/
A slender dog of a fast-running breed used for racing or hunting.
The greyhound races across the field on its long, slender legs.

Etymology
Old English grighund already named this kind of dog. Its first element probably meant “bitch,” though its origin is unknown; the familiar association with the colour grey reflects a later interpretation of the name.
