I’m so happy that Feanor didn’t change his name in Beleriand the same way his brothers did, or it’d probably be something horrible, like “Fincurufin”
FINfincurufin. MORE FINWE than they!
But I suppose “Spirit of Fire” was too cool to give up. Speaking of which, we don’t have mother names for Fingolfin or Finarfin, do we? *ponders* Ideas?
Granted, I may be missing something, but I can’t remember any right now.
Arakáno (like Argon) for Fingolfin, Ingoldo (earlier: Ingalaurë) for Finarfin, as per The Shibboleth of Fëanor, “The names of Finwë’s descendants” (HoME 12).
And yes, that makes “Gildor Inglorion of the House of Finarfin” in FotR very interesting indeed, even though he’s probs just another case of name-recycling.
ETA: Also Fëanor probably isn’t going to take any name-choosing cues from Fingolfin, who was apparently the first to do this – before the Flight of the Noldor, even, as the Shibboleth speculates that it may have been a major motivation behind Fëanor’s decision to burn the ships rather than let his half-brothers come over to Middle-earth.
