The word "birth" has many meanings.
The word "birth" has many meanings that are relevant in the abortion debate. For most people, the word "birth" only applies to the moment that a child emerges from or is surgically removed from the womb. The more specific word for that event is "parturition." It is worth noting that the root meanings of the word "birth" include Origin, Beginning, Any Coming into Existence and indeed "Conception." So, with those meanings in mind, when is a human organism actually "born?"
