Morphology

aboral = oral (semi-transparent) = ab + oral

Formally built from 'ab-' (away from) + 'oral', so the composition is clear, but 'aboral' is a technical biological term and the prefix 'ab-' (used for spatial 'away from') may be unfamiliar to general learners.

Etymology

Aboral comes from the parts a- 'away' and oral 'mouth', so it helps to remember it as 'away from the mouth'. In biology, aboral means the side or end of an animal that is opposite the mouth, for example the top of a starfish or the back of a sea urchin.
