Panayotis Koupitoris (Greek: Παναγιώτης Κουπιτώρης, Arvanitika: Πανάjοτ Κουπιτόρι/Panajot Kupitori, 1821-1881[1]) was a writer from the island of Hydra.
In 1879 Koupitoris purchased a printing press and, along with Anastas Kullurioti, started the publication of the newspaper The Voice of Albania (Albanian: Zëri i Shqipërisë),[4] Koupitoris is the author of the Greek-language Meletai peri tis glossis kai tou ethnous Alvanias ("Studies on the Albanian language and people"), published in Athens in 1879.
[2] In his book "Αλβανικαί Μελέται ‐ Πραγματεία ιστορική και φιλολογική περί της γλώσσης και του έθνους των Αλβανών" (English: Albanian Studies - An historical and literary essay about the Albanian nation and his language) in where he presents the core elements of his beliefs, after analyzing historically and literary the Albanian entity, concludes about the Albanian language that "αναγκάζεται τις να κατατάξη αυτήν εις τον ελληνολατινικόν κλάδον και να ομολογήση ότι της αλβανικής γλώσσης το πλείστον μέρος εστίν ελληνικόν, πολύ δε και το λατινικόν, σμικρόν δε τι μέρος το γερμανικόν και ελάχιστον το κελτικόν" (we have to classify it to the Greek-latin (linguistic) sector and to confess that the Albanian language is: mostly Greek, enough Latin, a little Germanic and at the minimum Celtic) p. 35.
[6] About the origin of the Illyrians and their language which he believes they were a relative to the Albanian, nation, he concludes: "Eκ των παρατεθειμένων συμπεραίνεται νομίζω ότι η ιλλυρική γλώσσα ην ουχί αλλότρια της ελληνικής, αλλά διάλεκτος αυτής απωτέρα των άλλων και οι Ιλλυριοί ελληνικόν φύλον."
[7] He also wrote a study about the pronouns of the Albanian dialect in Greece and an extended Latin-Greek lexicon.
