A fruit is botanically, a mature ovary of a plant.
There are fleshy fruits, and dry fruits, depending on whether the mature ovary develops Soft matter (flesh) or a more Solid composition.
There are also Accesory fruits (aka false fruits) where the fleshy part of the fruit is mostly developed from tissue other than the ovary. This includes Strawberryes and Pome (Fruit)s.

Taxonomy of botanical fruits
- Fleshy fruits
- Simple fruits, from a flower that has a single ovary.
- Berry, kernel, or endocarp is not very large..
- Drupe, the kernel is very large, and called stone.
- Pome. Accessory fruit composed of one or more carpels (but belonging sharing a single ovary! and so belonging to same pistil) surrounded by accessory tissue (the floar tube). E.g. Apple (only the middle comes from the carpels/ovary). E.g. Peach, Cherry
- Aggregate fruits, the fusion of several ovaries from a single flower. E.g. Strawberry (accesory), Raspberry (each of the components is called a drupelet)
- Multiple fruits, the fusion of several ovaries from multiple flowers. E.g. Pineaple
- Dry fruit

As you can see the distinction between berry and drupe is not that clear, and in fact the Avocado is sometimes classified as one or the other.
