Think of the word as carrying a body inside it. Latin corpus means body, and corporeal is built straight off it. So the word always stands on one side of a line, with something else on the other: body against soul, matter against spirit, the thing you can touch against the thing you can only think about. When you meet corporeal, the useful question is not what it means on its own but what it is being set against in that sentence. The answer is nearly always mind, soul or spirit.
From the word’s history
