Is cake a sort of bread? - Lemmy

So according to Merriam Webster bread is: a usually baked and leavened food made of a mixture whose basic constituent is flour or meal And cake is: A: a breadlike food made from a dough or batter that is usually fried or baked in small flat shapes and is often unleavened B: a sweet baked food made from a dough or thick batter usually containing flour and sugar and often shortening, eggs, and a raising agent (such as baking powder) And yet some people don’t think that cake is bread. What’s your opinion?

Bread usually has yeast, a cake never does.
What about pancakes?
They aren’t a cake, and they don’t have yeast either
