Balkan languages refer to a group of languages spoken in the Balkan Peninsula, primarily including Albanian, Bulgarian, Greek, Macedonian, Romanian, and Serbian. These languages exhibit unique features due to historical interactions and cultural exchanges among the diverse ethnic groups in the region. The Balkan Sprachbund, or linguistic area, highlights the shared grammatical and phonological traits among these languages, despite their different origins. This phenomenon illustrates how languages can influence each other through proximity and social contact, creating a rich tapestry of linguistic diversity in the Balkans.
