Morphology

avulsion = avulse (opaque) = avulse + ion

The medical sense derives from the rare verb 'avulse' and uses specialized anatomical meaning, making it non-obvious to average learners.

Etymology

Avulsion comes from the Latin verb avellere, from ab- 'away' and vellere 'to pull'. Think of it as 'pulling or tearing away', which is why doctors call a tooth or other body part an avulsion when it has been forcibly torn off.
