A judgment is an opinion that you have or express after thinking carefully about something.

Judgment is the ability to make sensible guesses about a situation or sensible decisions about what to do.

A judgment is a decision made by a judge or by a court of law.

If something is against your better judgment, you believe that it would be more sensible or better not to do it.

If you pass judgment on someone or something, you give your opinion about it, especially if you are making a criticism.

If you reserve judgment on something, you refuse to give an opinion about it until you know more about it.

To sit in judgment means to decide whether or not someone is guilty of doing something wrong.
