Morphology

pentamerous = pentamer (semi-transparent) = penta + mer + ous

Formation from the noun 'pentamer' with the productive adjectival suffix '-ous' is a regular and predictable derivation.

Etymology

The word pentamerous combines penta- meaning 'five', like in pentagon, and -merous meaning 'part' or 'segment', so it literally describes something 'made of five parts'. That's why a pentamerous flower has five petals and a pentamerous sea star has five arms.
