The Dwarvish tribe of northwestern Middle-earth, also known as Durin’s Folk (PM/321). The name translates as “Longbeard”, a compound of and “long” and fang “beard” (PM/321). The name also appears in its plural form Enfeng and its class-plural Anfangrim (PM/321, WJ/10).
Conceptual Development: In the Lost Tales and the earliest Silmarillion drafts this tribe was called the G. Indrafang (LT2/68, SM/104). In the Gnomish Lexicon from the 1910s, the variant form G. Surfang or Fangsur also appeared (GL/68). The name was later changed to N. Enfeng (plural) in Silmarillion drafts from the 1930s (LR/274), and the singular form N. An(d)fang appeared in The Etymologies (Ety/ÁNAD, SPÁNAG).
The name S. Enfeng appeared in Silmarillion revisions from the 1950s-60s (WJ/10, 75), but did not appear in the published version of The Silmarillion. The name was referenced in some notes to Tolkien’s essay “Of Dwarves and Men”, composed around 1969, along with Khuzdul and Quenya translations (PM/321).
