findor

masculine name. Findor

An earlier birth name of Gil-galad, but Tolkien marked this name with a “?” indicating he was uncertain of it (WJ/56). This name may contain the element fin seen in the Sindarin names of the descendants of Q. Finwë, combined with the suffix -dor “✱king, lord”. His later birth name is given as Ereinion (S/154).
