The Word Slumped

The word slumped means lacking in energy, usually after a long period of exertion. To be slumped is to lean or to lie or to sit; your body is completely lifeless as if you've just died or passed out. For example, to be slumped over to slump over a desk. You can imagine someone slumped over their desk because they've been studying English so hard that they've passed out. In those Victorian detective story episodes, I'm sure the word slumped came up.
