Are you going to that meeting tomorrow?

Root Explanation

Obligatory → It is formed from "ob-" (meaning towards) and "ligare" (meaning to bind). The word "obligatory" means something that binds you towards a duty or requirement.

Memory Tip

Think of being 'bound' ('ligare') to do something 'towards' ('ob-') — that's why obligatory means you have to do it.
