Morphology

seizure = seize (semi-transparent) = seize + ure

Derived from 'seize' plus '-ure' but extended metaphorically to a specialised medical episode where the body is 'seized'; the link is figurative and domain-specific.

Etymology

Seizure in medicine uses the same basic idea: it comes from the verb seize meaning 'to grab' or 'take hold'. So a medical seizure is when something suddenly 'takes hold' of the body or brain, causing an attack.
