Morphology

polymyositis = myositis (semi-transparent) = poly + myo + itis

Adding poly- transparently changes 'muscle inflammation' to inflammation affecting multiple muscles.

Etymology

Polymyositis comes from Greek parts: poly- 'many', myo- 'muscle', and -itis 'inflammation', and you can see poly- in polygon which means 'many sides' and -itis in arthritis which means 'joint inflammation'. So polymyositis is inflammation of many muscles, which is why it causes muscle weakness and pain.
