Unsuspected → It is formed from "un-" (meaning not) and "suspect" (from Latin "suspicere", meaning to look up at or to suspect). The word "unsuspected" means not suspected or not regarded as suspicious.
Think of 'not' ('un-') and 'looking up at' ('suspect') to remember that 'unsuspected' means something that is not regarded with suspicion.
