Morphology

harden = hard (transparent) = hard + en

The verb 'harden' is transparently derived from 'hard' with the suffix '-en' indicating the process of becoming or making hard.

Etymology

Harden comes from the old English word hard meaning 'not soft' and the ending -en that means 'make'. So to harden something is to 'make it hard', which fits uses like paint or cement becoming solid.
