Nastaliq, also romanized as Nastaʿlīq or Nastaleeq, is one of the main calligraphic hands used to write the Perso-Arabic script and it is used for some Indo-Iranian languages, predominantly Classical Persian, Kashmiri, Punjabi (Shahmukhi) and Urdu. It is often used also for Ottoman Turkish poetry, but rarely for Arabic. Nastaliq developed in Iran from naskh beginning in the 13th century and remains widely used in Iran, Afghanistan, India, Pakistan, and other countries for written poetry and as a form of art.
