Morphology

ferric = iron (opaque) = ferr + ic

Although 'ferric' refers to iron (Fe3+), the combining form 'ferr-' is not a standalone English word and is not transparently recognisable to average learners.

Etymology

Ferric comes from the Latin ferrum, which means 'iron', and the chemical symbol Fe also comes from ferrum. In chemistry, ferric names the form of iron with a '3+' charge, so the origin helps you remember it is about iron.
