Morphology

degrade = grade (semi-transparent) = de + grade

The formation de- + grade ('lower a level') is clear, but the geological sense ('be worn down') may be less obviously derived from 'grade' for some learners.

Etymology

Degrade comes from the parts de- 'down' and gradus 'step'. Think of land losing its 'steps' as rain and wind wear it away, so to degrade land is to lower its surface.
