paragraph_text: Hübschmann je 1875. dokazao da armenski nije samostalna grana iranskih jezika (prije se tako smatralo zbog velikog utjecaja iranskih jezika na armenskoga tijekom povijesti), već samostalna grana indoeuropske jezične skupine.<ref>[https://web.archive.org/web/20151221145559/http://www.utexas.edu/cola/centers/lrc/books/read12.html A Reader in Nineteenth Century Historical Indo-European Linguistics: On the Position of Armenian in the Sphere of the Indo-European Languages, Utexas.edu, 20. ožujka 2007., pristupljeno 19. srpnja 2019.]<ref>[http://www.enciklopedija.hr/natuknica.aspx?id=26583 Heinrich Hübschmann na Hrvatskoj enciklopediji, pristupljeno 19. srpnja 2019.] Koristio je komparativnu metodu kako bi razdvojio iranske posuđenice koje čine veličinu armenskih riječi od starijega sloja domaćih armenskih riječi.<ref>Rüdiger Schmitt, Harold Walter Bailey, 2011., Iranian influences in Armenian Language, Encyclopædia Iranica, pristupljeno 19. srpnja 2019. "The revolutionary element in Hübschmann’s procedure was that according to him Arm. words fully or largely agreeing with Ir. forms in phonetic shape were suspect of being loanwords and could therefore not safely be regarded as genuine Arm. words. It was due to this methodological principle, which only gradually gained universal acceptance, that Hübschmann became the significant pioneer in the study of Ir. borrowings in Armenian."
