Morphology
commissurotomy = commissure (opaque) = commissure + otomy
The form literally means 'cutting of a commissure', but both 'commissure' and the medical combining suffix '-otomy' are rare/specialized, so an average learner cannot derive the meaning from familiar components.
Etymology
Commissurotomy comes from the parts commissure which means 'joining' and -otomy which means 'cutting', as in lobotomy. So it literally means 'cutting a join', which is why a commissurotomy cuts the connections between the two sides of the brain to help control severe seizures.
