The Northwestern Iranian Languages are a branch of the Iranian languages, which are part of the larger Indo-Iranian language family. This group primarily includes languages spoken in northwestern regions of Iran, as well as parts of Iraq and Turkey. Notable languages in this category include Kurdish, Gilaki, and Mazandarani. These languages share common linguistic features and historical roots, reflecting the cultural and ethnic diversity of the area. They are characterized by unique phonetic, grammatical, and vocabulary elements, which distinguish them from other Iranian languages. The preservation and study of these languages are important for understanding the region's history and cultural heritage.
