oyster (English)

Where does "oyster" come from?

The English word 'oyster' traces its lineage through Middle English 'oystre', drawing from both Old English 'ostre' and Anglo-Norman 'oistre'[1][6]. These forms ultimately trace back through Old French 'oistre' to the Latin 'ostrea'[1][4][5][6]. Further back, the Latin term descends from the Ancient Greek 'ὄστρεον'[1][5][6].

The ancient Greek term is traditionally assumed to be related to the word for bone, but this connection has been rejected in favor of a Pre-Greek origin. [3]
