Morphology

Cycadopsida = cycad (semi-transparent) = cycad + opsida

The word is formed from 'cycad' plus the technical taxonomic suffix '-opsida'; the relation to 'cycad' is clear but the specialized suffix meaning 'class' is unfamiliar to average learners.

Etymology

Cycadopsida comes from cycad (a palm-like seed plant) and the ending -opsida, a scientific label you can think of as a 'group' or 'class'. So Cycadopsida simply means the class or group of cycad-like plants.
