Undoing → It is formed from "un-" (meaning not or opposite of) and "doing" (from Old English "don", meaning to perform or act). The word "undoing" refers to the act of reversing or negating a previous action or performance.
Think of 'un-' meaning not or opposite, and 'doing' meaning to perform an action. This helps you remember that 'undoing' means to reverse an action.
