Etymology
Origin of pineapple
1350–1400 for earlier sense; 1655–65 pineapple for def. 1; Middle English pinappel pine cone; see pine 1, apple
Explanation
A pineapple is a sweet tropical fruit with a tough leathery skin and spiky leaves on top. Pineapple is excellent, whether eaten as a snack, in a sweet dessert, in savory dishes like fried rice, or even on pizza. The word pineapple was first used to mean "pine cone," and the fruit was given this name because of its (slight) resemblance to a large pine cone. Pineapples are more commonly called ananas in other parts of the world, from the Tupi nanas, or "excellent fruit." Images of pineapples are commonly used to represent hospitality.
