A great river in eastern Beleriand (S/54). The meaning of the name is unclear. Given the river’s location in Ossiriand, this name might be <a href="../language-pages/lang-nan.html">Nandorin</a> instead.
Conceptual Development: The name N. Gelion first appeared in Silmarillion drafts from the 1930s as a revision of earlier Flend (SM/135). In the Etymologies, it is given as a Noldorin name glossed “Merry Singer”, a misinterpretation of its Ilkorin name gelion “bright” (Ety/GYEL). In later notes, Tolkien considered renaming the river to Gelduin >> Gevilon >> Gevelon, the last of these an adaptation of Khuzdul Gabilân “Great River” (WJ/336). He did not apply this change in the Silmarillion revisions from the 1950s-60s, however, so the gloss “Merry Singer” from the 1930s remains the best available translation of Gelion.
Variations of the word: Gelion, Gelduin, Gevilon, Gevelon.
Element in: S. Thargelion
