Root Explanation
Decay → It is formed from "de-" (meaning down or away) and "cadere" (meaning to fall). The word describes the process of something falling apart or deteriorating over time.
Memory Tip
Think of something 'falling down' ('de-' means down and 'cadere' means to fall) — that's why decay means to deteriorate.
