Oppilate is formed from "ob-" (meaning against) and "pallere" (meaning to be pale or to grow pale). The word describes the act of blocking or obstructing, as if causing something to become pale or diminished in presence.
Think of something being 'blocked' or 'obstructed' ('ob-') which makes it seem 'pale' or less visible ('pallere'). This helps you remember that 'oppilate' means to obstruct.
