A vegetarian is someone who doesn't eat any meat, including fish. Many vegetarians eat plenty of fruits and vegetables — but others subsist on pizza and mac and cheese.

This is a word that has to do with diet — what people eat. Vegetarians avoid meat, usually for health reasons, for environmental reasons, or because they believe it's wrong to kill animals for food. Vegetarians will eat some animal products, like eggs and dairy, but vegans won't. Both vegetarian and vegan diets are becoming more common. Many animals are vegetarians, including our close relative, the gorilla.
