Morphology

avascular = vascular (semi-transparent) = a + vascular

For learners who know 'vascular', the medical prefix 'a-' can suggest absence, but this is a technical pattern rather than an everyday English one.

Etymology

Avascular comes from the prefix a- meaning 'without' and vascular, which comes from a root meaning 'vessel' and is like the common word vessel. So, avascular means 'without vessels', and in medicine it describes tissue that has no blood vessels.
