Morphology

reharden = harden (transparent) = re + hard + en

The prefix 're-' clearly adds the meaning 'again' to the familiar verb 'harden'.

Etymology

Reharden is made of re- 'again' and harden 'to make hard'. So it means to become or make hard again, as when wax or metal hardens after it cools.
