If you say, "my family — they're crazy," you're probably talking about a group of people who are related to you by blood or marriage. Sometimes the word family specifically means a group of parents and children, so you could be referring to your crazy parents or kids.

Family is used many different ways. It can mean "household," or the people you live with, or it can refer to a partner and the children you are raising together. Your family can include people you've never met, like distant cousins, if you're using it to talk about the wider group of all of your relatives. There's also the scientific term family, which is a term that ranks the way different organisms are related to each other.
