Compound fruit

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".^[1]

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.
