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 (see feminism) (see also feminism) and liberals generally support the pro-choice side; Roman Catholics and Protestant fundamentalists generally back the pro-life side. (See Roe versus Wade.)

Etymology

Origin of abortion

First recorded in 1540–50, abortion is from the Latin word abortiōn- (stem of abortiō ). See abort, -ion

Explanation

Abortion is a medical procedure that ends a pregnancy. In the United States, the public debate over a women's right to have an abortion is a complex and heated political issue. The words abort and abortion can also apply to non-pregnancy related topics. If you are in the middle of a jewel-heist and the alarm on the vault is tripped, you and your partners in crime might opt to abort the plan and run while you can, debating whether the plan's abortion was a good decision or not later.
