Morphology

phycobilin = phyco + bilin

The term is a technical biochemical formation (phyco- + bilin) using specialised combining forms unfamiliar to average learners, so its meaning is not derivable from common English morphemes.

Etymology

Phycobilin comes from phyco- meaning 'seaweed' or 'algae' and -bilin from a word for 'bile' that later meant 'pigment'. So, phycobilin is literally an 'algae pigment', which fits because it is the coloured molecule in algae that helps them catch light to make energy.
