The word 'informer' means a person who tells someone in authority, like the police or the government, about something illegal or harmful that they have seen or heard. It is often used to describe people who help the authorities to solve crimes or prevent them from happening. For example, if someone saw someone stealing something from a store and they told the police, they might be called an informer. It is important to note that being an informer can be both positive and negative, depending on the situation, and it is always important to use good judgment when deciding whether to inform authorities of something.
