§ Elements in Quenya and Sindarin Names The Silmarillion

kal' (gal-) This root, meaning 'shine', appears in Calacirya, Calaquendi, Tar-Calion; galvorn, Gil-galad, Galadriel. The last two names have no connexion with Sindarin galadhtree', although in the case of Galadriel such a connexion was often made, and the name altered to Galadhriel. In the High-elven speech her name was Al(a)táriel, derived from alata 'radiance' (Sindarin galad) and riel 'garlanded maiden' (from a root rig- 'twine, wreathe'): the whole meaning 'maiden crowned with a radiant garland', referring to her hair. calen (galen) 'green' is etymologically 'bright', and derives from this root; see also aglar.
