A bystander is a person who is present during an event but is not directly involved in it. For example, if there is a fight going on in the street and you are just watching, you are a bystander. The word is often used in the context of witnessing something and not taking action to help or prevent it. Bystanders can play an important role in situations like bullying, where speaking up can make a difference.
