Etymology

Partly from a dialectal form of down; and partly from French dune (from Old French dune), or from Middle Dutch dūne (modern Dutch duin), or from Middle Low German dûne; all ultimately from Proto-West Germanic *dūn, *dūnā, probably from Proto-Celtic *dūnom (“stronghold, rampart”), from Proto-Indo-European *dʰuHnom (“enclosure”), from *dʰewh₂- (“to finish, come full circle”). Doublet of down (which see).
