Surface Forms
Morphology
periosteum = peri + oste + um
The parts are Greek combining forms used in medical terminology and are not transparently meaningful to an average B1 learner, so the overall meaning is specialist and not directly derivable from common English base words.
Etymology
Periosteum comes from the Greek parts peri- ('around') and osteon ('bone'), and the peri- is the same 'peri' in perimeter meaning 'around'. So the periosteum is the thin cover 'around the bone' that protects the bone and helps it heal.
