Domergue Sumien (in Occitan Domergue Sumien, in French Dominique Sumien; born July 5, 1968, in Compiègne, France) is an Occitan linguist and writer.
He used to work in the International Association for Occitan Studies (AIEO).
[2] Sumien is working towards the improvement of a standard written Occitan, named „broad Occitan“ (occitan larg) as initially defined by Louis Alibert, Robèrt Lafont, and Patrick Sauzet [fr; ca; oc].
As a member of the Occitan Language Council, he co-wrote a new set of recommendations for the orthography of standard Occitan.
[3] In his PhD thesis,[4] he enlarged his vision of a standard language and he also proposed to define some regional standards as he presents Occitan as a pluricentric language.
