Younger brother of Ar-Inziladûn (Q. Tar-Palantir) who was the 24th ruler of Númenor (S/269). His son Ar-Pharazôn usurped the throne to become the 25th (and final) ruler of Númenor. The first element of his name, gimil means “stars”, but it is not clear what last element means.
Adûnaic
gimil
collective noun. (all) stars; ?silver
gimilkhâd
masculine name. Gimilkhâd
gimilnitîr
feminine name. Star-kindler
A title of the goddess Avradî (Q. Varda) translated “Star-kindler” (SD/428), and therefore the Adûnaic equivalent of S. Gilthoniel. The first element gimil means “stars”, and the second is an agental-formation for the verb nitir- “to kindle” (SD/427-8).
gimilzagar
masculine name. ?Sword of Stars
gimilzôr
masculine name. Star-?foam
Gimilzôr was the Adûnaic name of Elros (SD/380) in the story “The Notion Club Papers” from the mid-1940s. Since the element gimil means “stars”, this name is most likely a translation of the Sindarin name, which means “Star-foam”.
In later writings, Gimilzôr is the son of Ar-Sakalthôr and the 23rd ruler of Númenor, whose Quenya name was Tar-Telemnar (S/268). It is unclear whether this instance of Gimilzôr retains the same meaning as the earlier version of the name. It is possible that the later version has the same meaning as Telemnar (translated by most authors as “Silver-fire”), in which case Tolkien may also have revised the Adûnaic name of Elros (the word for “foam” was elsewhere given as Ad. roth). Alternately, it could be that the Adûnaic and Quenya names are unrelated, and Tar-Telemnar simply adopted the Adûnaic name of his illustrious ancestor.
Andreas Moehn suggested (EotAL/KH-B-L) that if Gimilzôr means “Silver-fire”, its initial element gimil “silver” could be a cognate of Dwarvish kibil. Carl Hostetter and Patrick Wynne suggested (AAD/11) that his Quenya name Telemnar contains adjective ᴹQ. telemna “of silver”, and does not involve “fire” at all.
Conceptual Development: As a name for Eärendil, this name first appeared as Indilzar (SD/363).
Gimilzagar
Gimilzagar
Gimilzagar seems to mean "Star-sword" in Adûnaic (from gimil, 'star' and zagar, 'sword').
A collective-noun meaning “all the stars of the heavens”, as opposed to gimli which was used for an individual star (SD/427). The element gimil appears in many names, including several later names in The Lord of the Rings and The Silmarillion. Carl Hostetter and Patrick Wynne suggested (AAD/15) that it may be related to the Elvish root √(Ñ)GIL “shine (white)”.
Andreas Moehn suggested (EotAL/KH-B-L) that if the later name Gimilzôr means “Silver-fire”, its initial element gimil could instead mean “silver”, perhaps as a cognate of Dwarvish kibil. If so, this alternate meaning could either be a homonym of gimil “stars”, or a new meaning for gimil in Tolkien’s later works.
