The term "Hindko" is a Pashto word most commonly taken to have originally meant "the Indian language" or "language of Hind", but it has developed to denote the Indo-Aryan speech forms spoken in the northern Indian subcontinent, in contrast to the neighbouring Pashto, an Iranian language. Hindko is mutually intelligible with Punjabi and Saraiki, and has more affinities with the latter than with the former. Differences with other Punjabi varieties are more pronounced in the morphology and phonology than in the syntax.
