Morphology

carotenoid = carotene (semi-transparent) = carotene + oid

Formed from 'carotene' + the scientific suffix '-oid' meaning 'like/related to', but '-oid' is technical and may be unfamiliar to average learners.

Etymology

Carotenoid comes from the common word carrot and the ending -oid, which means 'like'. These pigments were named for the bright orange of carrots, so carotenoids are the yellow-to-red pigments found in plants and some animals.
