Morphology

keratinocyte = keratin (semi-transparent) = keratin + ocyte

Formed from 'keratin' + the technical combining form '-ocyte' meaning 'cell'; the relation is direct but '-ocyte' is specialized and may be unfamiliar to general learners.

Etymology

Keratinocyte comes from keratin, a word that originally meant 'horn', and -cyte, which means 'cell'. So a keratinocyte is a cell that makes keratin, the hard, horn-like protein that forms the skin's outer layer and helps protect the body.
