Morphology

nefarious = nefar (opaque) = nefar + ious

The root 'nefar' is not a productive English word and the adjective is a learned borrowing, so learners cannot reliably derive the meaning from its parts.

Etymology

Nefarious comes from the Latin word nefas, which meant 'wrong' or a 'crime' and is made from ne- ('not') plus fas ('what the gods allow'). So, nefarious describes actions that are not allowed and are deeply evil or criminal today.
