Use the adjective corporeal to describe something that has to do with the body, like when your teacher catches you daydreaming and says you need to bring your mental sharpness, not just your corporeal presence to the classroom.
Corporeal describes something that has a physical form. It is the opposite of spiritual or emotional. Something that is corporeal exists in the real world. It’s sort of a fancy way of saying bodily or physical. So when you crave double-cheese pizza with sausage and pepperoni, you could blame it on a corporeal need. (It’s a way to make junk-food cravings sound a little bit grand!)
