Whether it’s unjustified violence, an unjustified complaint, or an unjustified belief, you can use the word unjustified when something just isn’t right or seems to have no reason behind it.

When you break apart the word unjustified, it’s easy to see what it means. You’re probably familiar with the prefix un-, which here means “not.” And justified contains just, meaning “fair.” So something that's unjustified is not fair or not right, such as an unjustified action like damaging someone's property or the unjustified praise for someone who has taken credit for another person's efforts.
