borlach

masculine name. ?Steadfast-flame

Son of Bór, an Easterling in Beleriand (S/157). His name is appears to be a combination of [N.] bôr “steadfast” and lach “flame” “flame” (as suggested by David Salo, GS/344). As this name was Sindarin, it was probably not his true name.

Conceptual Development: In Silmarillion drafts from the 1930s, this name first appeared as N. Boromir, changed to Borlach in Silmarillion revisions from the 1950s-60s (LR/134, WJ/240).
