oyster: [14] The Greek word for ‘oyster’ was óstreon – etymologically an allusion to its shell. It came from a prehistoric Indo-European base *ost- denoting ‘bone’, which also produced Greek ostéon ‘bone’ (source of the English prefix osteo-), ostakós ‘crustacean’, and óstrakon ‘shell, piece of broken pottery’ (source of English ostracism). Óstreon passed into Latin as ostrea, and from there came by way of Old French oistre into English as oyster.
