Dardic languages
The Dardic languages (also Dardu or Pisaca) are a group of Indo-Aryan languages largely spoken in the northwestern extremities of the Indian subcontinent. Dardic was first formulated by George Abraham Grierson in his Linguistic Survey of India but he did not consider it to be a subfamily of Indo-Aryan. The Dardic group as a genetic grouping (rather than areal) has been scrutinised and questioned to a degree by recent scholarship: Southworth, for example, says "the viability of Dardic as a genuine subgroup of Indo-Aryan is doubtful" and "the similarities among [Dardic languages] may result from subsequent convergence".
