Morphology

saponify = sapon (opaque) = sapon + ify

The base 'sapon' is not a standalone English word, so the derivation is not transparent to most learners.

Etymology

Saponify comes from the Latin root sapo which means 'soap' and the suffix -ify which means 'make'. So, to saponify is to 'make' something into soap, which fits the chemical process of turning fat or oil into soap.
