What if a potato is placed in a perfect blender with apples? Apples are not potatoes, but when they are mixed with potatoes, what are they?

The word potato may have multiple meanings. A type of root is the most common, but calling something or someone a potato can mean a certain appearance or intellect. This renders that target as concurrently both potato and not potato.

Potato practically means "thing that is viable for a recipe that calls for a potato" or "thing that a restaurant customer will find acceptable as a potato". I'd be fine being served a sweet potato if I ordered a potato, but my friend wouldn't.

Potatoes aren't elementary particles. This means that potatoes are also not potatoes.

What about part of a potato? the atoms within a potato? a potato is an illusion. the universe is one thing. namaste.

what about hash browns and french fries

How about a fraction of a potato? If I cut a potato in half, it does not constitute a whole potato and therefore not **a** potato (but rather part of one), but, at the same time, is still made of potato, and is therefore potato. Therefore, it is not black and white.

Assuming the universe is infinite, there are infinite possibilities of "things" existing. Therefore, there is "something" within the universe that is simultaneously a potato and not a potato. "Schrodinger's potato" if you will.
