Did you know we have to attend the meeting compulsorily this week?

Root Explanation

Compulsorily → It is formed from "compuls-" (from Latin "compellere", meaning to drive together or force) and "-ory" (meaning relating to or characterized by). The word "compulsorily" means in a manner that is forced or required.

Memory Tip

Think of being 'driven together' ('compuls-') to do something 'relating to' ('-ory') a requirement — that's why compulsorily means you must do it.
