late 14c., pin-appel, "pine cone," from pine (n.) + apple. The reference to the fruit of the tropical plant (from resemblance of shape) is recorded by 1660s, and pine-cone emerged 1690s to replace pineapple in its original sense except in dialect. For "pine-cone," Old English also used pinhnyte "pine nut." Pine-apple also was used in a late 14c. Biblical translation for "pomegranate."
