Root Explanation
Prolongation → It is formed from "pro-" (meaning forward) and "longare" (meaning to make long). The word refers to the act of making something longer or extending its duration.
Memory Tip
Think of moving something 'forward' ('pro-') to make it 'longer' — that's why prolongation means extending something.
