Q. Umbardacil m. “Conqueror of Umbar”
A name assumed by the 28th kings of Gondor to celebrate his conquest of Umbar (LotR/1038, 1048). This name is a combination of Umbar and the suffix -(n)dacil “-victor, -slayer”, also seen in Hyarmendacil and Rómendacil. It was translated by Christopher Tolkien as “Conqueror of Umbar” (UTI/Telumehtar).
