Calion, Tar-Calion, masc. name, the Quenya name of King Ar-Pharazôn "the Golden". Calion would seem to be connected to cal- "shine", cálë "light". (Silm)
Quenya
calion
masculine name. *Son of Light
Calion
the golden
Caliondo
rock
Caliondo, masc. name, maybe a longer form of Calion above (unless Caliondo contains ondo "rock") (UT:210)
tarcalion
tarcalion
tarcalion = Tar-Calion, masc. name, Quenya name of Ar-Pharazôn (LR:47, SD:246); see Calion
Tar-culu
gold
Tar-culu ("k"), name listed in the Etymologies but not elsewhere attested. The second element is apparently culu "gold" (a word Tolkien seems to have abandoned); Hostetter and Wynne suggest that this may be an alternative name of Tar-Calion (= Ar-Pharazôn "the Golden"); see VT45:24.
culo
gold
[culo, culu ("k")noun "gold" (substance)] (KUL, VT49:47; the word culu_ also occurred in early "Qenya" [LT1:258], but in the Etymologies it was struck out; the regular Quenya word for "gold" is apparently _malta. In another version, culo meant "flame" [VT45:24], but this is apparently also a word Tolkien abandoned.)
laurë
gold
†laurë noun "gold", but of golden light and colour, not of the metal: "golden light" (according to PE17:61 a poetic word). Nai laurë lantuva parmastanna lúmissen tengwiesto "may (a) golden light fall on your book at the times of your reading" (VT49:47). In Etym defined as "light of the golden Tree Laurelin, gold", not properly used of the metal gold (LÁWAR/GLÁWAR, GLAW(-R), VT27:20, 27, PE17:159). In early "Qenya", however, laurë was defined as "(the mystic name of) gold" (LT1:255, 258) or simply "gold" (LT1:248, 268). In Laurelin and Laurefindil, q.v., Laurenandë "Gold-valley" = Lórien (the land, not the Vala) (UT:253) and laurinquë name of a tree, possibly *"Gold-full one" (UT:168). Laurendon "like gold" or "in gold fashion" (but after citing this form, Tolkien decided to abandon the similative ending -ndon, PE17:58).
malta
gold
malta noun "gold", also name of tengwa #18 (Appendix E). The Etymologies (entry SMAL) instead has malda, q.v. for discussion, but according to VT46:14, the form malta originally appeared in the Etymologies as well. Also compare the root MALAT listed in PM:366.
Tar-Calion was the Quenya name of Ad. Ar-Pharazôn, the last king of Númenor. This name seems to be a compound of cala “light” and the patronymic suffix -ion “-son” (S/270).
Conceptual Development: This character’s name was first given as ᴹQ. Angor, but the name was quickly changed to ᴹQ. Tar-Kalion (LR/27). In the Addenda and Corrigenda to The Etymologies, there is a name ᴹQ. Tar-kulu that the editors suggested could be an otherwise unattested variant of Tar-Calion (EtyAC/KUL).
A primitive form of this name, ✶Kalajondo, appeared in some linguistic notes from the 1950s (PE21/76).
