Morphology

deteriorate = deterior + ate

The segment 'deterior-' is a non-productive combining form and not a standalone English word, so learners cannot reliably derive the meaning 'become worse' from familiar morphemes.

Etymology

Deteriorate comes from the Latin deterior, which meant 'worse'. So to deteriorate is to 'become worse' or to go down in quality, condition, or value.
