Morphology

fiendish = fiend (semi-transparent) = fiend + ish

The sense 'extremely difficult' is a figurative extension from 'fiend' (diabolical) to mean 'diabolically hard', which is not a literal composition and may not be obvious to all learners.

Etymology

Fiendish comes from fiend ('devil') and -ish ('like'), and people also used it for clever, evil tricks. A helpful way to remember this is to imagine a puzzle made by a devil, so fiendish can mean 'very difficult' or made to confuse you.
