Morphology
cretaceous = cret + aceous
The word uses a classical chalk-related root plus the suffix -aceous, but the root is not a standalone English word and the meaning is not recoverable for an average learner.
Etymology
Cretaceous comes from the Latin word creta, meaning 'chalk'. So cretaceous describes rocks or soils that are full of chalk, like the white, chalky cliffs you can imagine.
