S. Ulfast m.
Son of the traitorous Easterling chief Ulfang (S/157). This name seems to be Sindarin, and therefore was probably not his true name. It seems to be a combination of (N.) ul- “*ugly” and (N.) fast “shaggy hair”.
Conceptual Development: This character was named N. Ulfast in Silmarillion drafts from the 1930s (SM/300, LR/287) and appeared in The Etymologies as a combination of ᴹ√ULUG and N. fast, the source of the derivation given above (Ety/ÚLUG, PHAS).
