In this episode we uncover Celtic fortresses among the sand dunes. A dune is a ridge or hill of sand piled up by the wind. It comes from Proto-West Germanic *dūn(ā) (sand dune, hill), via French or Dutch, from Proto-Germanic *dūnaz (accumulation, pile, heap, mound), or from Gaulish dunum (hill), from Proto-Celtic *dūnom (stronghold, rampart), all of which come from Proto-Indo-European *dʰuHnom (enclosure) [source]. Related words in the modern Celtic languages include: dún [d̪ˠuːnˠ] (fort(ress), place of refuge, residence, house) in Irish dùn [duːn] (fortress, heap) in Scottish Gaelic doon [duːn] (fort, stronghold) in Manx din [dɪn] (city, fortress, stronghold), and dinas (city) in Welsh din [di:n] (fort) in Cornish din [ˈdĩːn] (fortress) in Breton Apart from dinas in Welsh, these words are mostly found in placenames, such as Dún Dealgan (Dundalk) in Ireland, Dún Dè(agh) (Dundee) in Scotland, Dinbych (Denbigh) in Wales, Dinmeur (Dunmere) in Cornwall, and Dinan in Brittany. Words from the same Celtic roots possibly include town and down (a [chalk] hill, rolling grassland) in English, tuin (garden, yard) in Dutch, tún (hayfield) in Icelandic, and тын [tɨn] (fence [especially one made of twigs]) in Russian [source]. Words same PIE roots include dusk, dust and fume in English, dagg (dew) and dy (mud, mire, sludge) in Swedish, and fem (dung, manure) in Catalan [source].
