Proto-West Germanic

Alternative forms

• *dūn m, *dūnu f, *dūnō m

Etymology

Uncertain and disputed; possibly from Proto-Germanic *dūnaz (“accumulation, pile, heap, mound”) (whence also Old Norse dúnn (“pile, heap, assembly”)), from Proto-Germanic base *dū- (“to whisk, whip up, excite, agitate, storm, be stormy”), from Proto-Indo-European *dʰewh₂- (“smoke, dust, haze”). Unlike permanent hills, sand dunes are ever-shifting due to storms and wind, and are not optimal places to build fortifications.
Alternatively, perhaps borrowed from Proto-Celtic *dūnom (“stronghold, rampart”), from the same Proto-Indo-European root above, which also developed the sense of "hill, fortified hill" in Brythonic; however phonology makes a borrowing from Brythonic untenable, as the vowel there shifted from ū to i giving Proto-Brythonic *din where Germanic still clearly has ū.
