I picked up a copy of Mark T. Hooker's collection of essays
A Tolkienian Mathomium at Oxonmoot this year, and I've very much enjoyed reading it despite the harsh light it threw on my ignorance. Hooker is a professional linguist and gives an interesting insight into the workings of Tolkien's jokes. I'll give some examples from his essays below by way of a taster.
In 'The Linguistic Landscape of Tolkien's Shire', Hooker examines the place-name
Dwaling. Now, as any fule kno,
-ing in an English place-name usually indicates the home of people descended from a common ancestor: hence
Reading (
Readingum = 'Settlement of Réada's people'), Nottingham (
Snotengaham = 'Settlement of Snot's People'). Hooker suggests that in
Dwaling, the first component of the name (the personal name of the tribe's original founder) is a shortened form of
Dwalakoneis, which is just the Gothic form of 'Tolkien'. Hence 'Tolkien's people' or 'ancestral home of Tolkien's people'. Looking at a map of the Shire, Dwaling would be some distance north-north-west of Buckland, which in the real world is south-south-west of Evesham in Worcestershire. Tolkien associated his Suffield ancestors with Evesham, and his brother ran a fruit farm there for many years. One of the significant landmarks of this area is Bredon Hill (
Bree-dún = 'Hill-hill'), which contains the same element that gave Bree its name.
Hooker devotes an entire essay to explaining the derivation of
Carrock. He reveals this to be an anglicised form of Welsh
carreg, which means 'stone', 'rock' or 'escarpment'. One famous
carreg in the Black Mountains of Carmarthenshire is
Carreg Cennen, which has a castle on it that some legends say was founded by one of King Arthur's knights. Hooker takes these two facts (and various topographical similarities between Beorn's Carrock and the Welsh location) and then throws in a good joke. If, following the usual pattern of such words in Welsh, we make a compound out of the Welsh for 'bear' (
arth) and the Welsh for 'man' (
gwr), we get
arthwr.
The very hills are laughing on Tolkien's maps.
