1. noun The belief that every human being has the right to live. The phrase is often used in discussions of war, abortion, and capital punishment, among other topics. I believe in the right to life, and I'm not going to debate that with you, since you clearly support legalized abortion. How can we claim to believe in the right to life and also support the war effort?

2. adjective Holding such beliefs. Often hyphenated. Yes, I am a member of a right-to-life group, as that cause is very important to me. The right-to-life issues are always the ones that trip up politicians.
