Morphology

diabolic = diabol + ic

The element 'diabol-' is a non‑transparent combining form (from Latin/Greek for 'devil') that is not a standalone English word and does not map form‑for‑form to 'devil', so learners cannot reliably derive the meaning from familiar English bases.

Etymology

Diabolic comes from the Greek word diabolos, which first meant 'slanderer' and later became the name for the 'devil'. That's why diabolic means extremely evil or cruel — like something a devil would do.
