Urdu alphabet
The Urdu alphabet is based on the Persian, which is an Arabic alphabet. Urdu is written from right to left, and most letters link together. This leads to variations in the form of a letter depending on its position in a word. Most vowels are omitted in generic texts, although they may be written for disambiguation or for pedagogical purposes. Urdu is primarily written in a calligraphic style of the script called Nasta'liq.
