A vegetarian is someone who doesn't eat any meat, including fish. Vegetarians eat a lot of salads.
This is a word that has to do with diet — what people eat. A vegetarian avoids meat, usually because it's healthier or they believe it's wrong to kill animals for food. Vegetarians will eat some animal products, like eggs and dairy, but vegans won't. Being vegan is harder than being a vegetarian, but both diets are becoming more common. Many animals are vegetarians, including our close relative, the gorilla.
