Sindarin form of Q. Ingalaurë, mother-name of Finarfin (PE17/118), possibly invalid due to later changes (see below).

Conceptual Development: In Silmarillion drafts from the 1930s, N. Inglor was the given name of Felagund (LR/116, 254), but sometime between the publication of the 1st and 2nd editions of The Lord of the Rings, Tolkien changed his given name to S. Finrod (MR/181 note §41-2). At one point, Tolkien repurposed Inglor as a hypothetical Sindarin name of Felagund’s father Finarfin, a translation of his mother-name Q. Ingalaurë, but “this was not actually applied to [Finarfin] who never came to Beleriand” (PE17/118).

Later still, Finarfin’s mother-name was changed to Q. Ingoldo (PM/360), at which point the name S. Inglor may have been removed from the legendarium, though it perhaps survived as the name of the father of Gildor: see Inglorion.

See S. Felagund for a table of the conceptual development related names.

In Silmarillion drafts from the 1930s, this name appeared as the true Elvish name of Felagund “Lord of Caves”, which was his title as the lord of Nargothrond (LR/116). In The Etymologies, Inglor was given as a derivative of ᴹ✶Indo-ʒlaurē, in effect a compound of N. ind “heart” and N. glaur “gold”, so “*Heart of Gold”.

Conceptual Development: See S. Felagund for a discussion of the conceptual development of this and related names, and see S. Inglor for the later developments of this name.
