Morphology

suspicious = suspect (transparent) = suspect + ious

A standard adjectival formation from 'suspect' with the productive suffix '-ious', so learners who know 'suspect' can infer the meaning.

Etymology

Suspicious comes from old Latin parts sus- 'under' and specere 'to look', and it is related to suspect and words like inspect that have the same 'look' root. So, something suspicious makes you 'look closely' because it seems wrong or dangerous.
