@TheEdVerse in faerun, how would the surname Blackrose translate into elven? If at all?

1/2) It does. Here we go…In Faerûn Elvish, the relevant words are:
Narl = black
Oumrae = dark, eerie
Imbur = dusk, sooty, shadowed
And a rose is a “thornflower,” so:
Spir = thorn, spike [pronounced “spear”] 2/2)
Aulauth = flower, blossom
Hence aulauthspir = rose
So Blackrose is usually rendered “Narlauthspir” but over time, SOME usages of the surname have been corrupted/shortened into Nalauthspir or Nauthspir or even Nothspir/Nothspir/Nuthspur#Realmslore

P.S. Many elves who live and work among humans (i.e. members of an adventuring band) adopt a “humans can call me this” surname that’s a portmanteau of a hue and a living thing/natural feature (like Blackrose, or Bluewater).#Realmslore
