Etymology: "Godsibling" is a plural form, so it is the plural of "godsibling", a compound built from "god-" and "sibling". The "god-" element here is the familiar English prefix that marks a relationship through a godparent, as in "godfather" and "godmother," so a godsibling is a child who shares a godparent with you. The word puts the sibling relationship on the godparent side of a family, which is why the two parts fit together so neatly.
