What does grison mean?
Grison most often refers to a small, long-bodied carnivorous mammal native to South America. The best-known member of the genus is the common grison, scientifically known as Grison guara and also called the tayra; another species is the lesser grison. These animals have short legs, short ears, and gray or brown coats, and despite their raccoon-like appearance they belong to the weasel family, Mustelidae. The word also has an old and now largely obsolete equestrian sense: a gray or chestnut horse. Consequently, historical texts may use grison in a context unrelated to wildlife, while modern readers will usually understand it as a zoological term. Grison is relatively uncommon outside specialist writing, but it is useful when distinguishing South American mustelids or reading older English. The related name tayra is particularly frequent for the common grison and should not be treated as applying equally to every species in the genus.

The usual plural is grisons. The capitalized form Grison is used when referring to the zoological genus.

Despite its raccoon-like appearance, a grison belongs to the weasel family, the same family as weasels, badgers, and otters.

Etymology of grison
The zoological term entered English from French grison, formed from Old French gris, meaning “gray,” with the suffix -on. English had already used grison for a gray or chestnut horse, a color-related sense that preceded its specialized zoological use. French derivatives such as grisette and grisaille continue to share the same gray-related root.
How grison is actually used
In modern English, grison is chiefly a specialist zoological term. The older sense meaning a gray or chestnut horse is archaic and chiefly encountered in historical writing.
