plaice: [13] The plaice is etymologically the ‘broad’ fish. Its name goes back ultimately to Greek platūs ‘broad’ (which makes it distantly related to place). From this was descended, via some missing links, late Latin platessa ‘flatfish’, which became Old French plaïs – whence English plaice. => place, plate, platypus[plaice etymology, plaice origin, 英语词源]
