dune

Etymology

In the OED's revised account it is borrowed from Dutch duin,^[2] earlier Middle Dutch dūne and Old Dutch dūn,^[2][3][4] probably going back ultimately to the same Celtic base as the hill sense of down.^[2] Most other dictionaries take it as borrowed from French dune, from dune, which is itself from Middle Dutch,^{[5][6][4][7][8]} and Etymonline leaves open whether it came from French, Middle Dutch or Middle Low German dūne.^[9] The French word, recorded from about 1195, was borrowed from Dutch, as were German Düne, Italian duna, Spanish duna, Danish dyne and Swedish dyn.^[2] The Celtic base is seen in Gaulish dūnon (“fortified enclosure, hill fort”), found in place names, Welsh din (“fortress”), Breton din (“fortress”) and Old Irish dún (“fortress”);^[2] Barnhart reconstructs Gaulish *dūnom and relates it to Old English tūn, the source of town.^[8][9] The OED notes that the Old Dutch word has sometimes been explained as a borrowing from dūn (“hill”) brought to Flanders by Anglo-Saxon settlers in the 11th century, but that much earlier place-name evidence tells against this.^[2] Etymonline adds that the English word may partly be a dialect form of down.^[9]

Earliest recorded meaning

A mound or ridge of sand heaped up by the wind: 1605, in Verstegan's A Restitution of Decayed Intelligence.^[2] Barnhart, Etymonline and Merriam-Webster date the word to 1790,^[8][9][6] and the Shorter Oxford and the Oxford Dictionary of English to the late 18th century.^[4][7]

Semantic evolution

The meaning has stayed close to the Dutch one, a hill of loose sand, especially by the sea; the OED adds hills of other loose sediment, and dunes in deserts as well as on coasts.^[2][4] Merriam-Webster notes dunes along some river valleys and wherever dry surface sand lies for part of the year.^[6] The compound dune buggy, a vehicle for driving on beaches and sand, is recorded by 1965.^[9]
