The Balkan languages were the first group of languages whose similarities were explained in modern linguistic terms as a result of language contact rather than as a result of descent from a common ancestor. Nikolai Trubetzkoy coined the term Sprachbund ‘linguistic league’ (as opposed to Sprachfamilie ‘language family’) to describe this relationship. Balkan linguistics, as both a subset of and precursor to contact linguistics, is, at its base, an historical linguistic discipline. It seeks to explain similarities among the relevant languages as the result of diffusion rather than of either transmission or of putative universal, typological properties of human language (which latter assumes parallel developments whose causation is ahistorical, i.e., unconnected with either contact or ancestry). The relevant languages are, with the exception of Turkic, all part of the Indo-European language family, but they belong to five distinct groups that are known to have been separated for a significant length of time (presumably millennia). Moreover, for four out of five Indo-European groups, as well as for Turkic, there exists documentation that goes back more than a millennium, and in some cases several millennia. The Balkan languages are thus the oldest example of a well-documented and still living Sprachbund.
The primary questions that Balkan linguistics seeks to answer are these: What are the results of language contact in the Balkan languages, and how did they come about? The Balkan languages are traditionally defined as Albanian, Modern Greek, Balkan Romance (Romanian, Aromanian, and Meglenoromanian), and Balkan Slavic (Bulgarian, Macedonian, and the southernmost dialects of the former Serbo-Croatian). In recent decades, it has been recognized that the relevant dialects of Romani, Judezmo, and Turkish and Gagauz also participate in at least some of the convergent processes that are taken as definitive of the Balkan linguistic league. While the language family is defined by regular sound correspondences, which in turn help define shared morphology and a core lexicon, the Balkan linguistic league is defined principally by shared morpho-syntactic developments and a shared lexicon of borrowings often called “cultural.” In the Balkan linguistic league, phonological developments are sometimes shared among different languages at the dialectal level, but there are no such features that characterize the Balkan languages as a group. Just as in the language family, not every diagnostic item is represented in every branch, so, too, in the Balkan linguistic league, not every feature is equally represented in all languages and dialects.
Among the most characteristic morpho-syntactic features are the following: (a) replacement of infinitives by analytic subjunctives; (b) the use of a particle derived from etymological “want” to mark the future; (c) replacement of synthetic gradation of adjectives with analytic constructions; (d) replacement of conditionals by anterior futures; (e) post-posed definite articles (for Balkan Slavic, Balkan Romance, and Albanian); (f) resumptive clitic pronouns for certain direct and indirect objects; (g) various simplifications in the declensional system; and (h) grammaticalized evidentials (Balkan Slavic, Albanian, to some extent Balkan Romance and Romani, Turkic). While some of these convergences began in the ancient or medieval periods, the Balkan linguistic league took its definitive modern shape during the centuries of the Ottoman Empire (14th to early 20th centuries).
