Indo-Iranian languages
Indo-Iranian is a branch of the Indo-European language family comprising the Indo-Aryan, Iranian, and Nuristani language groups.
Indo-European languages: A language family whose branches include Indo-Iranian, Germanic, Romance, and Slavic. Indo-Iranian is one of this family's major branches.
Proto-Indo-European language: The reconstructed ancestor of the Indo-European language family. Proto-Indo-Iranian descended from this earlier reconstructed language.
William Jones: An eighteenth-century British judge and scholar whose work helped establish the relationship among Sanskrit, Greek, and Latin. His observations helped prompt systematic comparison of Indo-European languages, including Indo-Iranian.
Sanskrit: An ancient Indo-Aryan language that remains central to Hindu, Buddhist, and Jain texts and scholarship. Its classical literature and grammar became influential across South Asia.
Dravidian languages: A language family including Tamil, Telugu, Kannada, and Malayalam, spoken mainly in South Asia. Dravidian languages are distinct from Indo-Iranian despite extensive contact and borrowing.
Nuristani languages: A small group of languages spoken mainly in eastern Afghanistan and neighboring areas of Pakistan. Nuristani forms the third principal branch alongside Indo-Aryan and Iranian.
Indo-Iranian migrations: The movements of Indo-Iranian-speaking populations across Central and South Asia in prehistory. These migrations help explain the branch's spread across a vast region.
Franz Bopp: A German linguist who pioneered comparative grammar of Indo-European languages. His comparisons helped place Sanskrit and Iranian languages within a shared historical framework.
Persian language: An Iranian language spoken in forms including Iranian Persian, Dari, and Tajik. Persian became a major literary and administrative language across western and central Asia.
Uralic languages: A language family including Finnish, Estonian, and Hungarian, with no established genetic relationship to Indo-European. Similarities from contact do not make Uralic languages part of Indo-Iranian ancestry.
