Etymology: "Birthparent" is a plain compound: "birth" joined to "parent." "Birth" traces back to Old Norse "byrðr," meaning "birth" or "being born," related to the verb "bear" in the sense of giving birth, while "parent" comes from Latin "parens," the one who begets or gives birth. Joining the two produced a term that points specifically to the biological parent, the person whose bearing or begetting started the child's line. The compound is useful mainly because English otherwise blurs the distinction. "Parent" can mean a mother or father who raises a child, adopts one, or stands in as a guardian, so a separate word was needed when the genetic origin matters. The added "birth" narrows the meaning to that original link, whatever happened afterward.
