Arbitrary is a word used when something seems chosen without a clear reason, rule, or fair system. It often appears in school writing, legal discussions, decisions, rules, and everyday criticism.
If a number, rule, punishment, deadline, or choice feels random, people may call it arbitrary. The word is a little formal, but its meaning is easy: the choice does not seem based on logic or clear evidence.
