Etymology
the word 'flatfish' is a transparent english compound, formed from the adjective 'flat' and the noun 'fish'. 'flat' originates from proto-germanic flataz, likely from the proto-indo-european root plat-, meaning 'to spread', which also gave rise to greek 'platus' (broad) and latin 'platus' (flat). 'fish' derives from proto-germanic fiskaz, from pie peysk- (fish). the compound directly and logically describes the primary anatomical characteristic of these marine creatures—their dorsoventrally flattened bodies—which is a key adaptation for life on the sea floor.
