Origin of HobbitFrom Hobbit a trademarked name for a member of a race of humanlike creatures about three feet tall that appear in the works of J.R.R. Tolkien
The word hobbit has an unknown origin. However, as designating a diminutive legendary creature, it fits seamlessly into a category of English words in hob- for such beings. The Middle English word hobbe has manifested in many creatures of folklore as the prefix hob-. Related words are : hob, hobby, hobgoblin, Hobberdy Dick, Hobberdy, Hobbaty, hobbidy, Hobley, hobbledehoy, hobble, hobi, hobyn (small horse), hobby horse (perhaps from Hobin), Hobin (variant of the name Robin), Hobby (nickname for Robert), hobyah, Hob Lantern.
The only source known today that makes reference to hobbits in any sort of historical context is the Denham Tracts by Michael Aislabie Denham. More specifically, it appears in the Denham Tracts, edited by James Hardy, (London: Folklore Society, 1895), vol. 2, the second part of a two-volume set compiled from Denham's publications between 1846 and 1859.
The text contains a long list of sprites and bogies, based on an older list, the Discovery of Witchcraft, dated 1584, with many additions and a few repetitions. The term hobbit is listed in the context of boggleboes, bogies, redmen, portunes, grants, hobbits, hobgoblins, brown-men, cowies, dunnies.
The most famous use comes from J.R.R. Tolkien in 1937, featuring in the novels The Hobbit and The Lord of the Rings. Ostensibly from a hypothetical Old English *holbytla "hole-builder".
Probably from hoppet, hobbet, (a basket).
