Morphology
opsin = ops (opaque) = ops + in
The element 'ops' is a technical combining form not found as a standalone common English word; combined with the technical suffix '-in' it forms a specialised scientific term.
Etymology
Opsin comes from the Greek opsis 'sight', the same root behind optics, and scientists borrowed this name for similar light-sensitive proteins found in microbes. These microbial opsins act like tiny light switches that let researchers control cells with light.
