Dari comes from
Middle Persian which was spoken during the rule of the
Sassanid dynasty. In general, Iranian languages are known from three periods, usually referred to as Old, Middle, and New (Modern) periods. These correspond to three eras in Iranian history, the old era being the period from some time before, during, and after the
Achaemenid period (that is, to 300 BCE), the Middle Era being the next period, namely, the Sassanid period and part of the post-Sassanid period, and the New era being the period afterward down to the present day. The first person in Europe to use the term
Deri for
Dari may have been
Thomas Hyde in his chief work, (1700).
Dari or
Deri has two meanings. It may mean the language of the court: : "the Zebani Deri (Zeban i Deri or Zaban i Dari = the language of Deri), or the language of the court, and the Zebani Farsi, the dialect of Persia at large (...)" It may also indicate a form of poetry used from
Rudaki to
Jami. In the fifteenth century it appeared in Herat under the Persian-speaking
Timurid dynasty. The Persian-language poets of the
Indian subcontinent who used the Indian verse methods or rhyme methods, such as
Bedil and
Muhammad Iqbal, became familiar with the
araki form of poetry. Iqbal loved both styles of literature and poetry, when he wrote: This can be translated as: : Even though in euphonious
Hindi is sugar – : Rhyme method in Dari is sweeter usually means 'bliss', 'delight', 'sweetness'; in language, literature and poetry, also means 'euphonious' or 'melodic'. Referring to the 14th-century Persian poet
Hafez, Iqbal wrote: English translation: : All the parrots of India will crack sugar : Through this Persian Candy which is going to Bengal Here ('
Rock candy of Persia') is a metaphor for the Persian language and poetry. Persian replaced the Central Asian languages of the
Eastern Iranic peoples. Ferghana, Samarkand, and Bukhara were starting to be influenced by Dari, and were originally
Khwarezmian and
Sogdian-speaking areas during
Samanid rule. Dari Persian spread around the Oxus River region, Afghanistan, and Khorasan after the Arab conquests and during Islamic-Arab rule. The replacement of the Pahlavi script with the Arabic script in order to write the Persian language was done by the
Tahirids in 9th century Khorasan. Dari Persian spread and led to the extinction of Eastern Iranian languages such as
Bactrian and Khwarezmian with only a tiny amount of Sogdian descended
Yaghnobi speakers remaining, as the ancestors of
Tajiks started speaking Dari after relinquishing their original language (most likely Bactrian) around this time, due to the fact that the Arab-Islamic army which invaded Central Asia also included some Persians who governed the region like the
Sassanids. Persian was a prestigious high-ranking language and was further rooted into Central Asia by the Samanids. Persian also phased out
Sogdian. The role of lingua franca that Sogdian originally played was succeeded by Persian after the arrival of Islam. == Geographical distribution ==
