mallen
adjective. golden, golden, [N.] of gold
An adjective for “golden” mentioned in Tolkien’s “Unfinished Index” of The Lord of the Rings as an element in the name Cormallen “Golden Circle” (RC/625). It may also be seen in Rathmallen, a variant of the name Rathlóriel “Golden-bed”, replacing the second element glóriel “golden” with mallen (WJ/353). The word N. mallen also appeared in The Etymologies of the 1930s under the root ᴹ√SMAL “yellow” as an “analogical” variant of N. malthen “of gold” (Ety/SMAL).
Possible Etymology: In Tolkien’s later writings, this adjective was probably based on the root √MAL(AT) “gold”, also seen as the basis for the noun malt “gold [as metal]” (PE17/50; VT42/27). It was likely in keeping with the 1950s and 60s sound change whereby medial lth became voiceless ll; a similar sound shift may be seen in S. mallorn “golden tree” < OS. malthorn = malt + orn (VT42/27). In Noldorin of the 1930s lth was preserved, so 1930s N. mallen may have been based on ✱(s)maldina instead.
Neo-Sindarin: For purposes of Neo-Sindarin, I would use this word only for golden colors, and would use [N.] malthen for “of gold [metal]”; see that entry for discussion.

This appears to be an adjectival form of glaur “gold (colour or light)” seen only as a element in names like Galadlóriel “Golden Rain” (MR/155; RS/187) [not an exact translation] and Rathlóriel “Golden-bed” (S/235).
Conceptual Development: In The Etymologies of the 1930s these names had a short o under the root ᴹ√(G)LAWAR, indicating a Noldorin form of N. gloriel (Ety/LÁWAR). The Gnomish Lexicon of the 1910s had G. glôriol “golden, like gold” based on G. glôr “gold” (GL/40).
