mae govannen i was wondering if there is a feminine version of gil-galad because it means starlight/star of radiance (there was a few different translations) and that seems like it would also be a great name in the feminine form.
Gil-galad is inherently a unisex name; it was given to him as a title later in life. It's just the noun "starlight" used as a name.
If you want feminine names meaning starlight or radiant star, I can offer:
Quenya: Silmanel/Silmiel/Silmissë, Ilmanel/Ilmiel/Ilmissë, Silmaheri/Ilmaheri, Elveanel, Altélen(el)
Sindarin: Elgaladeth/Gilgaladeth, Elcheryn/Gilcheryn (these meaning star-lady), Aglarel(eth), Glaneleth/Glangileth
thank you these names are beautiful i especially love Altélen(el)/ Aglarel(eth)
