Root Explanation
Prerogative → It is formed from "pre-" (meaning before) and "rogare" (meaning to ask or propose). The word refers to a right or privilege that is exclusive to a particular individual or group, often granted before others.
Memory Tip
Think of having a special right or privilege that is 'before' ('pre-') others, as if it is something you 'ask for' ('rogare') first.
