Origin & History of “decoy”
Dutch kooi means ‘cage’ (it comes from Latin cavea ‘cage’, source of English cage). The term came to be applied specifically to a pond which had been surrounded with nets into which wildfowl were lured for capture. English took it over, but brought with it the Dutch definite article de, so that Dutch de kooi ‘the decoy’ became English decoy.
