Morphology

endosteum = osteum (opaque) = endo + osteo + um

The parts are classical medical combining forms (endo- 'within' + osteo-/osteum 'bone membrane') that are not productive or obvious to an average B1 learner, so the meaning is not derivable without specialized knowledge.

Etymology

Endosteum comes from the parts endo- meaning 'within' and oste- meaning 'bone', the same root you see in osteoporosis. So, endosteum is the thin lining 'inside' a bone's hollow that helps with bone growth and repair.
