Brahmic scripts
Historically, Hindustani was written in the Kaithi, Devanagari, and Urdu alphabets. Kaithi and Devanagari are two of the Brahmic scripts native to India, whereas the Urdu alphabet is a derivation of the Perso-Arabic script written in Nastaʿlīq, which is the preferred calligraphic style for Urdu.
