The Albanian–Romanian linguistic relationship is a field of the research of the ethnogenesis of both peoples. The common phonological, morphological and syntactical features of the two languages have been studied for more than a century. Both languages are part of the Balkan sprachbund. Aside from Latin, and from shared Greek, Slavic and Turkish elements, other characteristics and words are attributed to the Paleo-Balkan linguistic base: Illyrian, Thracian, Dacian and/or Thraco-Illyrian, Daco-Thracian. Similarities between Romanian and Albanian are not limited to their common Balkan features and the assumed substrate words: the two languages share calques and proverbs, and display analogous phonetic changes.
