What is porridge? is it like oatmeal?!

Porridge is a more general term that is not used much any more.

It could be oatmeal, or it could be cream of wheat, or it could be grits (wheat). The more modern general term is "hot cereal".

Some people mistakenly think porridge is different than oatmeal because they have only had instant oatmeal. If you go to a store and buy stone ground oatmeal, that will make porridge.

Americans don't eat much 'porridge' because of language drift.
The language spoken in America has drifted so far from mainstream (aka BRITISH) English that it is almost a completely different language.

Oatmeal IS porridge. Made the same way with the same ingredients, it's just that because of language drift Americans now use a completely different word to the rest of the English speaking world.
