I can't believe how some rules at work seem so arbitrary.

I know, right? It's like they just make things up on the spot.

That would definitely make things easier for everyone.

Root Explanation

Arbitrary → It is formed from "arbitrare" (meaning to judge or decide) and the suffix "-ary" (meaning pertaining to). The word "arbitrary" refers to decisions made based on personal judgment rather than any objective standard.

Memory Tip

Think of someone making a decision based on their own judgment ('arbitrare') — that's why arbitrary means based on personal choice.
