So it turns out that “berry” doesn’t mean what you think it means.
As the Wiki article points out, a berry “is a simple fruit having seeds and pulp produced from a single ovary”. Which means these are berries:
- Banana
- Watermelon
- Tomato
And these are not berries:
- Cherry
- Blackberry
- Raspberry
- Strawberry
- Halle Berry
Now you know.
