Do you consider oatmeal to be cereal?

I think oatmeal is oatmeal and cereal is cereal. And a burger isn’t a sandwich.

Hot cereal is any porridge made with a grain. Oatmeal is specifically made from oats. Other forms of hot cereal are (for example) Cream of Wheat (wheat), polenta (corn), grits (corn), and others.
