Dari in the context of "Nimruz Province"

Persian, also known by its endonym Farsi or Parsi, is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, respectively Iranian Persian (officially known as Persian), Dari Persian (officially known as Dari since 1964), and Tajiki Persian (officially known as Tajik since 1999). It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivative of the Arabic script, and within Tajikistan in the Tajik alphabet, a derivative of the Cyrillic script.

Modern Persian is a continuation of Middle Persian, an official language of the Sasanian Empire (224–651 CE), itself a continuation of Old Persian, which was used in the Achaemenid Empire (550–330 BCE). It originated in the region of Fars (Persia) in southwestern Iran. Its grammar is similar to that of many European languages.

The Arabic script is the writing system used for Arabic (Arabic alphabet) and several other languages of Asia and Africa. It is the second-most widely used alphabetic writing system in the world (after the Latin script), the second-most widely used writing system in the world by number of countries using it, and the third-most by number of users (after the Latin and Chinese scripts).

The script was first used to write texts in Arabic, most notably the Quran, the holy book of Islam. With the religion's spread, it came to be used as the primary script for many language families, leading to the addition of new letters and other symbols. Such languages still using it are Arabic, Persian (Farsi and Dari), Urdu, Uyghur, Kurdish, Pashto, Punjabi (Shahmukhi), Sindhi, Azerbaijani (Torki in Iran), Malay (Jawi), Javanese, Sundanese, Madurese and Indonesian (Pegon), Balti, Balochi, Luri, Kashmiri, Cham (Akhar Srak), Rohingya, Somali, Mandinka, and Mooré, among others. Until the 16th century, it was also used for some Spanish texts, and—prior to the script reform in 1928—it was the writing system of Turkish.

Middle Persian, also known by its endonym Pārsīk or Pārsīg (Inscriptional Pahlavi script: 𐭯𐭠𐭫𐭮𐭩𐭪, Manichaean script: 𐫛𐫀𐫡𐫘𐫏𐫐‎, Avestan script: 𐬞𐬀𐬭𐬯𐬍𐬐) in its later form, is a Western Middle Iranian language which became the literary language of the Sasanian Empire. For some time after the Sasanian collapse, Middle Persian continued to function as a prestige language. It descended from Old Persian, the language of the Achaemenid Empire and is the linguistic ancestor of Modern Persian, the official language of Iran (also known as Persia), Afghanistan (Dari) and Tajikistan (Tajik).

Tajik, Tajik Persian, Tajiki Persian, also called Tajiki, is the variety of Persian spoken in Tajikistan and Uzbekistan by ethnic Tajiks. It is closely related to neighbouring Dari of Afghanistan with which it forms a continuum of mutually intelligible varieties of the Persian language. Several scholars consider Tajik as a dialectal variety of Persian rather than a language on its own. The issue of whether Tajik and Persian are to be considered two dialects of a single language or two discrete languages has political aspects to it.

By way of Early New Persian, Tajik, like Iranian Persian and Dari Persian, is a continuation of Middle Persian, the official administrative, religious and literary language of the Sasanian Empire (224–651 CE), itself a continuation of Old Persian, the language of the Achaemenid Empire (550–330 BC).

Afghans (Pashto: افغانان; Dari: افغان‌ها) are the citizens and nationals of Afghanistan, as well as their descendants in the Afghan diaspora. The country is made up of various ethnic groups, of which Pashtuns, Tajiks, Hazaras, and Uzbeks are the largest. The three main languages spoken among the Afghan people are Dari (a variety of Persian), Pashto, and Uzbek. Historically, the term "Afghan" was a Pashtun ethnonym, but later came to refer to all people in the country, regardless of their ethnicity after the 1964 Constitution of Afghanistan proposed by the King of Afghanistan, Mohammad Zahir Shah.

Tajiks (Dari: تاجیکان, Tajik: Тоҷикон), also spelled Tadzhiks or Tadjiks, are a group of various Persian-speaking Eastern Iranian groups of people native to Central Asia, living mainly in Afghanistan, Tajikistan and Uzbekistan. Even though the term Tajik does not refer to a cohesive cross-national ethnic group, Tajiks are the largest ethnicity in Tajikistan, and the second-largest in both Afghanistan and Uzbekistan. They speak variations of Persian, a west Iranian language. In Tajikistan, since the 1939 Soviet census, its small Pamiri and Yaghnobi ethnic groups are included as Tajiks. In China, the term is used to refer to its Pamiri ethnic groups, the Tajiks of Xinjiang, who speak the Eastern Iranian Pamiri languages. In Afghanistan, the Pamiris are considered a separate ethnic group.

As a self-designation, the literary New Persian term Tajik, which originally had some previous pejorative usage as a label for eastern Persians or Iranians, has become acceptable during the last several decades, particularly as a result of Soviet administration in Central Asia. Alternative names for the Tajiks are Fārsīwān (Persian-speaker), and Dīhgān (cf. Tajik: Деҳқон) which translates to "farmer or settled villager", in a wider sense "settled" in contrast to "nomadic" and was later used to describe a class of land-owning magnates as "Persian of noble blood" in contrast to Arabs, Turks and Romans during the Sassanid and early Islamic period.

Pashto (/ˈpʌʃtoʊ/,/ˈpæʃtoʊ/ PASH-toh; پښتو, Pəx̌tó, [pəʂˈto, pʊxˈto, pəʃˈto, pəçˈto]) is an eastern Iranian language in the Indo-European language family, natively spoken in northwestern Pakistan and southern and eastern Afghanistan. It has official status in Afghanistan. It is known in historical Persian literature as Afghani (افغانی, Afghāni).

Spoken as a native language mostly by ethnic Pashtuns, it is one of the two official languages of Afghanistan alongside Dari, and it is spoken as the second-largest provincial language in Pakistan, spoken mainly in Khyber Pakhtunkhwa and the northern districts of Balochistan. Likewise, it is the primary language of the Pashtun diaspora around the world. The total number of Pashto-speakers is at least 40 million, although some estimates place it as high as 60 million. Pashto is "one of the primary markers of ethnic identity" amongst Pashtuns.

The Persian alphabet (Persian: الفبای فارسی, romanized: Alefbâ-ye Fârsi), also known as the Perso-Arabic script, is the right-to-left alphabet used for the Persian language. It is largely identical to the Arabic script with four additional letters: پ چ ژ گ (the sounds 'g', 'zh', 'ch', and 'p', respectively), in addition to the obsolete ڤ that was used for the sound /β/. This letter is no longer used in Persian, as the [β]-sound changed to [b], e.g. archaic زڤان /zaβɑn/ > زبان /zæbɒn/ 'language'. Although the sound /β/ (ڤ) is written as "و" nowadays in Farsi (Dari-Parsi/New Persian), it is different to the Arabic /w/ (و) sound, which uses the same letter.

It was the basis of many Arabic-based scripts used in Central and South Asia. It is used for both Iranian and Dari: standard varieties of Persian; and is one of two official writing systems for the Persian language, alongside the Cyrillic-based Tajik alphabet.

Firozkoh (Pashto, Dari: فیروزکوه), formerly called Chaghcharan (Pashto, Dari: چغچران), and historically known as Ahangaran (Pashto, Dari: آهنگران), is a town and district in central Afghanistan, which serves as the capital of Ghor Province. It is located on the southern side of the Hari River, at an altitude of 2,230 m above sea level. Chaghcharan is linked by a 380 kilometres (240 mi) long highway with Herat to the west (following the south side of Paropamisus Mountains (Selseleh-ye Safīd Kūh)), and a 450 kilometres (280 mi) long highway with Kabul to the east. The town is served by Chaghcharan Airport.

Chaghcharan has a population of roughly 15,000 who are mostly Dari and Pashto speakers. However, data from 2015 showed a population of 31,266. It has 1 district and a total land area of 2,614 hectares. The total number of dwellings in the city is 3,474.

Ghōr (Pashto, Dari: غور) also known as Ghowr or Ghur, is one of the 34 provinces of Afghanistan. It is located in the western Hindu Kush in central Afghanistan, towards the northwest. The province contains eleven districts, encompassing hundreds of villages, and approximately 764,472 settled people. Firuzkoh (known as “Chaghcharan” until 2014) is the capital of the province.
