Prejudice refers to the attitudes and feelings—whether positive or negative and whether conscious or non-conscious—that people have about members of other groups.
A prejudice is a negative belief or feeling about a particular group of individuals. Prejudices are often passed on from one generation to the next.
Prejudice is a feeling towards a person based on their affiliation with a group.
When someone is prejudice it usually refers to their thoughts, feelings and beliefs about a certain group of people. These are not the attitudes that are practiced, but only what is cognitively or even subconsciously processed.
Example, a person may hold prejudiced views towards a certain race or gender etc. (e.g. sexist).
