Ar-Abattarik

Like the eighteen rulers of Numenor before him, the nineteenth took the Sceptre with a Quenya name, Tar-Ardamin. In private, though, the King's Men called him by a name in their own Adunaic language: Ar-Abattarik. This King was the last to follow the practice of using an official Quenya name. His son Ar-Adunakhor abandoned old traditions, and used Adunaic in his official name.
