Andúnië (apparently a variant form of andúnë) place-name, a city and port on the western coast of Númenor, said to mean "sunset". (Appendix A, Silm, UT:166, NDŪ/VT45:38)
andúniëplace name. Sunset
Conceptual Development: The name ᴹQ. Andúnie appeared in the earliest tales of Númenor, first as a name for Númenor itself (LR/14), but soon changing to the name of a major city of that land (LR/25). At one point Tolkien considered changing this name to ᴹQ. Undúnië, but he soon rejected the idea (SD/333, SD/340 note #2).
andúnësunset, west, evening
andúnë noun "sunset, west, evening" (NDŪ, Markirya, SA), also in Namárië: Andúnë "West" (but the standard Quenya translation of "west" is Númen) (Nam, RGEO:66) Cf. andu- in Andúnië, Andúril.
