Another name for Carcharoth, translated “Jaws of Thirst” (S/180). The name is a combination of anc “jaw” and faug “thirsty” (SA/faug), though the function of the final -lir is unclear.
Conceptual Development: In Silmarillion drafts from the 1930s, the name appeared as N. Anfauglin with the same translation (SM/115).
an(d) (“long”) + faug (“thirst”) + lîr (“row, range #of teeth”)
