Morphology
orthosis = ortho (semi-transparent) = orth + osis
The combining form 'ortho' suggests 'straight', giving a clue, but the suffix '-osis' typically marks medical conditions and the specific device sense is technical, so the relation is not fully transparent for average learners.
Etymology
Orthosis comes from the Greek root orth- meaning 'straight' or 'correct', the same root you see in orthopedic and orthodox. So an orthosis is a device that helps keep a limb or the spine in the right position, which is why it supports and aligns the body.
