Root Explanation
Pushdown → It is formed from "push" (from Old English "pyssan", meaning to exert force) and "down" (from Old English "dūn", meaning to a lower position). The word "pushdown" describes the action of exerting force to move something to a lower position.
Memory Tip
Think of using force ('push') to move something to a lower place ('down') — that's what pushdown means.
