Duna could be used as the strictly feminine form of Dune, used to refer to a sand hill formed by the wind in deserts or near coastal regions. The origin of the word comes from Middle Dutch dūne, which itself could possibly be derived from Gaulish dunum (hill) or from Proto-Celtic dunom (stronghold, rampart). It derives from PIE *dʰewh₂- (to close, finish, come full circle). Duna is also the Italian and Spanish word for dune. Duna is also an Icelandic feminine name, a variant of Dúnna which is the feminine form of Dúnn from Old Norse meaning “eider-down”, the name of a duck.
Duna is also the Hungarian name for the Danube river running through Central and Eastern Europe. Though the etymology behind the name is unclear, I’ve seen it listed as meaning “swift flowing” though it also means “river” from the Avestan word dānu meaning “river” deriving from a PIE root word.
