S. go-² pref. “*away” (Category: From, Away)
A hypothetical element in the name Gódhel, a late Sindarin replacement for Ódhel “Elf who left for Aman”, but Tolkien said “it seems most probable that it took g- from the old clan-name Golodh, pl. Goelydh, which it practically replaced” (WJ/364). Thus *go- “away” < ✶wā- is probably a false etymology.
