isildur

masculine name. *Servant of the Moon

The eldest son of Elendil from whom Aragorn was descended (LotR/1038). His name is a compound of Isil “Moon” and the suffix -(n)dur “servant” (SA/sil, Ety/NDŪ).

Conceptual Development: The earliest mention of this character named him ᴹQ. Árundil (SD/401). In Lord of the Rings drafts from the 1940s, this name first appeared as (Noldorin?) Ithildor >> Isildor (RS/271), soon revised to ᴹQ. Isildur (RS/320). The name Isildur also appeared in a marginal note in The Etymologies from the 1930s (Ety/NDŪ).
