Persian alphabet

The Persian alphabet is directly derived and developed from the Arabic alphabet. The Arabic alphabet was introduced to the Persian-speaking world after the Muslim conquest of Persia and the fall of the Sasanian Empire in the 7th century. Following this, the Arabic language became the principal language of government and religious institutions in Persia, which led to the widespread usage of the Arabic script. Classical Persian literature and poetry were affected by this simultaneous usage of Arabic and Persian. A new influx of Arabic vocabulary soon entered the Persian language. In the 8th century, the Tahirid dynasty and Samanid dynasty officially adopted the Arabic script for writing Persian, followed by the Saffarid dynasty in the 9th century, gradually displacing the various Pahlavi scripts used for the Persian language earlier. By the 9th-century, the Perso-Arabic alphabet became the dominant form of writing in Greater Khorasan.

Under the influence of various Persian Empires, many languages in Central and South Asia that adopted the Arabic script use the Persian Alphabet as the basis of their writing systems. Today, extended versions of the Persian alphabet are used to write a wide variety of Indo-Iranian languages, including Kurdish, Balochi, Pashto, Urdu (from Classical Hindustani), Saraiki, Panjabi, Sindhi and Kashmiri. In the past the use of the Persian alphabet was common amongst Turkic languages, but today is relegated to those spoken within Iran, such as Azerbaijani, Turkmen, Qashqai, Chaharmahali and Khalaj. The Uyghur language in western China is the most notable exception to this.

During the Soviet period many languages in Central Asia, including Persian, were reformed by the government. This ultimately resulted in the Cyrillic-based alphabet used in Tajikistan today. See: Tajik alphabet § History.

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. These include 28 letters of the Arabic alphabet, in addition to 4 other letters.

The names of the letters are mostly the ones used in Arabic except for the Persian pronunciation. The only ambiguous name is he, which is used for both ح and ه. For clarification, they are often called hâ-ye jimi (literally "jim-like he" after jim, the name for the letter ج that uses the same base form) and hâ-ye do-češm (literally "two-eyed he", after the contextual middle letterform ـهـ), respectively. There are eight Persian letters that are mainly used in Arabic or foreign loanwords and not in native words: ث, ح, ذ, ص, ض, ط, ظ, ع and غ. These eight letters are also commonly used only in proper names. Unlike Arabic, the Persian language does not have pharyngealization at all. Although the letter غ is mainly used in Arabic loanwords, there are some native Persian words with this letter: آغاز, زغال, etc. The pronunciation of these letters in Persian can differ from their pronunciation in Arabic. For example, the letter ث is pronounced as /s/ in Persian, while it is pronounced as /θ/ in Arabic.

• Many Perso-Arabic scripts in South Asia share close similarities (use of Nastaliq, use of superscript ط to represent retroflex consonants, etc.) due to mutual contact during development. It is inaccurate to say that one Indo-Persian script directly descends from another, and instead, they are best seen as a cluster of scripts with common origin.
• However, the Arabic variant continues to be used in its traditional style in the Nile Valley, similarly as it is used in Persian and Ottoman Turkish.

Comparison of different numerals

Western Arabic		1	2	3	4	5	6	7	8	9	10
Eastern Arabic	٠	١	٢	٣	٤	٥	٦	٧	٨	٩	١٠
Persian	۰	۱	۲	۳	۴	۵	۶	۷	۸	۹	۱۰

1. U+0660 through U+0669
2. U+06F0 through U+06F9. The numbers 4, 5, and 6 are different from Eastern Arabic.
3. Same Unicode characters as the Persian, but language is set to Urdu. The numerals 4, 6 and 7 are different from Persian. On some devices, this row may appear identical to Persian.

Typically, words are separated from each other by a space. Certain morphemes (such as the plural ending '-hâ'), however, are written without a space. On a computer, they are separated from the word using the zero-width non-joiner.

As part of the russification of Central Asia, the Cyrillic script was introduced in the late 1930s. The alphabet has remained Cyrillic since then. In 1989, with the growth in Tajik nationalism, a law was enacted declaring Tajik the state language. In addition, the law officially equated Tajik with Persian, placing the word Farsi (the endonym for the Persian language) after Tajik. The law also called for a gradual reintroduction of the Perso-Arabic alphabet.^{[excessive citations]}

The Persian alphabet was introduced into education and public life, although the banning of the Islamic Renaissance Party in 1993 slowed adoption. In 1999, the word Farsi was removed from the state-language law, reverting the name to simply Tajik.^[1] As of 2004^[update] the de facto standard in use is the Tajik Cyrillic alphabet,^[2] and as of 1996^[update] only a very small part of the population can read the Persian alphabet.^[3]
