iodopsin singular

Morphology

iodopsin = opsin (opaque) = iodo + opsin

The combining form 'iodo-' (meaning 'violet') is a specialized scientific element unfamiliar to average B1 learners, so knowing 'opsin' alone is insufficient to derive the meaning.

Etymology

Iodopsin comes from iodo- meaning 'violet' and -opsin meaning 'sight', as in optics. So, the name points to a 'violet' pigment in the eye's cone cells that helps you see color in daylight.
