Etymology

Origin of vegetarianism

First recorded in 1850–55; vegetarian + -ism

Explanation

Do you enjoy veggie burgers, pasta primavera, and bean burritos but skip the beef, chicken, and fish? Then you're a proponent of vegetarianism, the practice of not eating meat. Vegetarianism is all about what someone chooses to include in their diet. A vegetarian doesn't eat meat or fish, and sometimes abstains from animal products like eggs as well. You might be interested in vegetarianism for health reasons or because you're concerned about animal welfare. Before the words vegetarian and vegetarianism were coined in the 19th century, people following this diet were referred to as anti-carnivorous.
