Partial birth meant partial birth not full birth, which allowed them to call it "abortion" instead of homicide (even though it is homicide in actuality); Infanticide was death of a fully born baby...something that everyone thought was homicide until a year or so ago, when the Left started to say it is ok.
The pro-abortion lobby had definitions. You are trying to rewrite those definitions just to win a point on an internet board, but history is history, and our posts can't change it.
