Perso-Arabic

The Persian alphabet (Persian: الفبای فارسی‎‎ alefbā-ye fārsi) or Perso-Arabic alphabet is a writing system based on the Arabic script and used for the Persian language. It has four letters more than the Arabic alphabet: پ [p], چ [t͡ʃ], ژ [ʒ], and گ [ɡ].

The Persian script is an abjad and is exclusively written cursively. That is, the majority of the letters in a word connect to each other. This is also implemented on computers. Whenever the Persian alphabet is typed, the computer automatically connects the letters to each other. Words are written from right to left. Also, vowels are underrepresented in writing; see below for details.

The replacement of the Pahlavi scripts with the Persian alphabet in order to write the Persian language was done by the Tahirid dynasty in ninth century Greater Khorasan.

Below are the 32 letters of the modern Persian alphabet. Since the script is cursive, the appearance of a letter changes depending on its position: isolated, initial (joined on the left), medial (joined on both sides), and final (joined on the right) of a word.
