Thus * hregwos became the ancient Greek Erebos. The gw sound became a b in Greek (for example, the Greek word basileus, meaning “king” comes from an earlier form gwasireu). (In linguistics, the asterisk indicates words that are not recorded anywhere but have been reconstructed based on related words or other forms.) The Proto-Indo-European language had several different consonants corresponding to the letter h, and the exact pronunciation of them all is a matter of debate, but before an r at the beginning of a word, this h regularly became an e in Greek. ( Erebos is the original Greek spelling it is often seen Latinized as Erebus.) To name an underground city cut out of the rock of a mountain, this makes sense as a starting point, but Erebos has an interesting etymology of its own.Įrebos derives from a Proto-Indo-European root * hregwos. The obvious place to start is Erebos, a name from Greek Mythology for both a region of the underworld and a primordial god representing darkness. Nevertheless, there are some clear real-world referents that we cannot ignore. By that point, Tolkien’s constructed languages were well developed and he provided a suitable internal etymology for Erebor as an Elvish translation of Lonely Mountain. The term Erebor did not appear until The Lord of the Rings. Even the few places with proper names are fairly transparent in their meaning: the town that sits in a dale by the Lonely Mountain is called Dale, and Mirkwood is not too hard to understand as a murky wood. Most of the places named in the novel have descriptions more than names-the Misty Mountains, the Long Lake, Lake Town. The Hobbit itself does not make much use of Tolkien’s linguistic experiments. Since Professor Tolkien was a linguist, and his Middle Earth was first inspired by his desire to create a world and history around his invented languages, it makes sense to ask what inspired him to name this important place Erebor.

Erebor, also known as the Lonely Mountain, is a lost kingdom of the Dwarves in Tolkien’s Hobbit, reclaimed from the dragon Smaug by Thorin Oakenshield and his companions, including Bilbo Baggins the Hobbit, at the end of the story.
