Nonexposed → It is formed from "non-" (meaning not) and "exposed" (from Latin "exponere", meaning to put out or expose). The word "nonexposed" means not put out or not exposed to view or danger.
Think of 'not' ('non-') and 'put out' ('exponere') to remember that 'nonexposed' means something that is not exposed.
