Morphology

delusion = delude (transparent) = delude + ion

Standard nominalization of the verb 'delude' with '-ion' yielding 'state or condition of being deluded', so the meaning is directly derived.

Etymology

Delusion comes from Latin parts de- and ludere, where ludere means 'to play'. So a delusion is like a 'play' or trick on the mind — a strong, false belief that fools you.
