The name Finrod is a Sindarin form of his Telerin (Quenya) name Findaráto, with the approximate meaning "Mighty descendant of Finwë". His mother name is Ingoldo ("the Ñoldo").[10]
Felagund is an epessë given to him by the Dwarves that expanded the caves of Nargothrond. It is actually of Dwarvish origin (or Sindarized Khuzdul) from the word felak-gundu ("Hewer of Caves").[11]
Finrod was also called by Bëor and his people Nóm ("Wisdom"), Nómin ("the Wise"), and "Friend-of-Men" which in elvish was Edennil and Atandil, Sindarin and Quenya respectively.[1][11]
