Is cereal a soup?

Welcome to the debate arena! Today's topic: "Is cereal a soup?". Your opponent's style: Aristotle

It depends, on the type of cereals for example if you add water in a bowl full of oat

You're cutting yourself off mid-thought, but I see where you're going, and it's exactly backwards. Adding water to oats doesn't make it soup, it makes porridge. That's a completely different category. Soup requires broth or stock as its foundation, a savory base built on meat, vegetables, and time. Cereal with milk is a sweetened breakfast dish, fundamentally different in purpose, preparation, and ingredient hierarchy. Water doesn't magically transform cereal into soup any more than soaking bread makes it a beverage. You're confusing texture with taxonomy. Just because something becomes wet and soft doesn't mean it changes its essential nature. Finish your argument properly, not that it'll save it.

What about a soup made of rice and water? don't you think that this could be labelled as a soup just the same?

A rice-and-water dish is barely soup at all, and it certainly doesn't prove cereal is one. That watery rice is what we call congee or porridge, depending on consistency, not soup. Real soup has intentional flavor development through broth, seasoning, aromatics. It's cooked with purpose beyond just softening grain. Your logic collapses here. You're saying "if thin rice can be soup, cereal can be too." But that argument works backwards just as easily: if cereal isn't soup, neither is your bland rice water. You haven't defined what actually makes something soup. Until you do, you're just naming wet things and hoping something sticks. What specifically makes your rice-water a soup?
