Did you see the options I sent you for the project?

Root Explanation
Unselected → It is formed from "un-" (meaning not) and "select" (from Latin "selectus", meaning chosen). The word "unselected" means not chosen or not picked out from a group.
Memory Tip
Think of 'not' ('un-') and 'chosen' ('select') to remember that 'unselected' means something that has not been chosen.
