Hindustani numerals

1-99

The numbers 1-99 largely evolved directly from the Sanskrit forms without being borrowed, and so are nearly all irregular.

For the number 0, Modern Standard Hindi tends to use śūnya (a Sanskrit tatsama) while Standard Urdu prefers sifr (borrowed from Arabic), though the native tadbhava-form is sunnā in Hindustani. Sometimes the ardha-tatsama form śūn is also used (semi-learned borrowing).
