abortion
The deliberate termination of a pregnancy, usually before the embryo or fetus is capable of independent life. In medical contexts, this procedure is called an induced abortion and is distinguished from a spontaneous abortion (miscarriage) or stillbirth.
Abortion laws are extremely controversial. Those who describe themselves as pro-choice believe that the decision to have an abortion should be left to the mother. In contrast, the pro-life faction, arguing that abortion is killing, holds that the state should prohibit abortion in most cases. Feminists (seefeminism) and liberals generally support the pro-choice side; Roman Catholics and Protestant fundamentalists generally back the pro-life side. (SeeRoe versus Wade.)
