Surreptitious → It is formed from "sur-" (meaning from below or secretly) and "rapere" (meaning to seize or take). The word describes something that is done secretly or stealthily, as if taken without notice.
Think of something being 'taken secretly' ('sur-' means from below or secretly, and 'rapere' means to seize). This helps you remember that 'surreptitious' refers to actions done in a hidden or sneaky manner.
