An angel is a special being that some people believe in. It is said that angels are pure and good and they are sent by God to help people. They are not like humans or animals, they are different. But we mostly think of them having wings, white clothes and a halo on top of their head, like in pictures or movies. Some people believe that angels are guardians, meaning they protect us from bad things happening to us. It is also said that they can bring messages from God or give comfort to people who are feeling sad. Even though you cannot see them, some people believe they are always around us to help and guide us.
