A neologism for “badger” coined by Paul Strack in 2021 based on ᴱQ. oryat (oryap-), to serve as a replacement for the somewhat improbable S. felagund “badger”.
Sindarin
felagund
noun. den-dweller; brock, badger
eriab
noun. badger
thindrostir
noun. badger
A word for “brock, badger”, more literally “den-dweller”, appearing in 1969 notes as a late etymology for the name Felagund (NM/304). In this scenario, the name “den-dweller” was given to Felagund somewhat derisively by the sons of Fëanor referring to his tendency to hide away in Nargothrond (NM/304). However, in The Sillmarillion as published, Christopher Tolkien used the explanation that the name was given to Finrod by the Dwarves and meant “cave-hewer”, based on marginal notes from 1959 in Tolkien’s copy of The Silmarillion itself (PM/352).
Neo-Sindarin: Since I prefer the Silmarillion origin for the name Felagund, I would not use this word for “badger”. I would instead suggest a neologism ᴺS. eriab based on ᴱQ. oryat (oryap-).
