Thanks, WikiMedia!
One of those rare plants that (like strawberries) the seed is external to the fruit. Said fruits are called cashew apples and supposedly are tasty. English got the name not via Portuguese but rather French acajou, and in the process the a was taken to be an indefinite article and separated off as "a cajou" -- French apparently got it directly from Old Tupi (though I'd expect a Portuguese intermediary?) akaƮu.
