Morphology

poliosis = polio (opaque) = polio + osis

Although formed from the combining form polio- (gray) + the medical suffix -osis, the combining form is not familiar to typical learners and the term is specialized medical vocabulary, so its meaning is not derivable by most users.

Etymology

Poliosis comes from the Greek word polios, meaning 'gray', plus the medical ending -osis for a 'condition'. So, poliosis is a condition where parts of the hair lose color and become white or gray.
