Etymology
From Middle English oystre, from Old English ostre, reinforced or superseded by Anglo-Norman oistre, which is from Old French oistre, uistre (compare modern French huître); both lines (Old English and Old French) from Latin ostrea, from Ancient Greek ὄστρεον (óstreon). Doublet of ostro (“a purple dye”).
Uncertain. Perhaps a nickname for someone who cultivated or sold oysters.
Webster’s 1913
- noun Any marine bivalve mollusk of the genus Ostrea. They are usually found adhering to rocks or other fixed objects in shallow water along the seacoasts, or in brackish water in the mouth of rivers. The common European oyster (Ostrea edulis), and the American oyster (Ostrea Virginiana), are the most important species.
- noun A name popularly given to the delicate morsel contained in a small cavity of the bone on each side of the lower part of the back of a fowl. Fresh-water oyster (Zoöl.), any species of the genus Etheria, and allied genera, found in rivers of Africa and South America. They are irregular in form, and attach themselves to rocks like oysters, but they have a pearly interior, and are allied to the fresh-water mussels.
