When a person has prejudice, it means that they decide they like or dislike something without knowing much about it. The word comes from the Latin "pre" (before) and "judge".
Types of prejudice[change]
The word "prejudice" is often used when people dislike another group of people that are different from them. They may decide they do not like them because of their skin colour (this is "racial prejudice"), religion (religious prejudice) or nationality. These are all serious prejudices which can lead to discrimination, hatred or even war.
Prejudice in popular culture[change]
Judges in a court of law should not be prejudiced when deciding whether someone is guilty. They should have an "open mind" so that they can make a fair decision. For example, if that person is the judge's friend then the judge would be prejudiced because he (or she) would not want his (or her) friend to get into trouble.
