A raspberry is an aggregate fruit.

A pineapple is a multiple fruit.

The term compound fruit is sometimes used when it is not clear which of several fruit types a fruit belongs to. A compound fruit is "composed of two or more similar parts".

A compound fruit may be:

• An aggregate fruit, in which one flower contains several separate ovaries, which grow together during development.
• A multiple fruit, in which several flowers, each with an ovary, develop into small fruits that grow together into a larger fruit.
• A simple fruit formed from a compound ovary.

Grapes grow in clusters, but are not compound fruits. Each grape is grown from one ovary in one flower, and they are not attached to one another. view more...
