Leitner's
Dardistan, in its broadest sense, became the basis for the classification of the languages in the north-west of the
Indo-Aryan linguistic area (which includes present-day eastern
Afghanistan, northern
Pakistan, and
Kashmir).
George Abraham Grierson, with scant data, borrowed the term and proposed an independent Dardic family within the
Indo-Iranian languages. However, Grierson's formulation of Dardic is now considered to be incorrect in its details, and has therefore been rendered obsolete by modern scholarship.
Georg Morgenstierne, who conducted an extensive fieldwork in the region during the early 20th century, revised Grierson's classification and came to the view that only the "Kafiri" (
Nuristani) languages formed an independent branch of the
Indo-Iranian languages separate from
Indo-Aryan and
Iranian families, and determined that the Dardic languages were unmistakably Indo-Aryan in character. For example
driga "long" in
Kalasha is nearly identical to
dīrghá in Sanskrit and
ašrú "tear" in Khowar is identical to the Sanskrit word. French
Indologist Gérard Fussman points out that the term Dardic is geographic, not a linguistic expression. Taken literally, it allows one to believe that all the languages spoken in Dardistan are
Dardic. It also allows one to believe that all the people speaking Dardic languages are
Dards and the area they live in is
Dardistan. A term used by classical geographers to identify the area inhabited by an indefinite people, and used in
Rajatarangini in reference to people outside Kashmir, has come to have ethnographic, geographic, and even political significance today. ==Classification==
