Question: What group of languages was the language spoken, written, or signed by Ahmad Shamloo a part of?

full_context: Document 1: Hafez: Hafez was born in Shiraz, Iran. His parents were from Kazerun, Fars Province. Despite his profound effect on Persian life and culture and his enduring popularity and influence, few details of his life are known. Accounts of his early life rely upon traditional anecdotes. Early tazkiras (biographical sketches) mentioning Hafez are generally considered unreliable. At an early age, he memorized the Quran and was given the title of Hafez, which he later used as his pen name. The preface of his Divān, in which his early life is discussed, was written by an unknown contemporary whose name may have been Moḥammad Golandām. Two of the most highly regarded modern editions of Hafez's Divān are compiled by Moḥammad Ghazvini and Qāsem Ḡani (495 ghazals) and by Parviz Natel-Khanlari (486 ghazals).Modern scholars generally agree that Hafez was born either in 1315 or 1317.  According to an account by Jami, Hafez died in 1390. Hafez was supported by patronage from several successive local regimes: Shah Abu Ishaq, who came to power while Hafez was in his teens; Timur at the end of his life; and even the strict ruler Shah Mubariz ud-Din Muhammad (Mubariz Muzaffar). Though his work flourished most under the 27-year rule of Jalal ud-Din Shah Shuja (Shah Shuja), it is claimed Hāfez briefly fell out of favor with Shah Shuja for mocking inferior poets (Shah Shuja wrote poetry himself and may have taken the comments personally), forcing Hāfez to flee from Shiraz to Isfahan and Yazd, but no historical evidence is available. He is said to have been in Timur's court, as Hafez wrote a ghazal whose verse says if this Turk accept his homage:
Document 2: Nader Naderpour: Among many Iranian poets who shaped up the New Persian Poetry or New Poetry (in Persian: "She'r-e Now"), Ali Esfandiari aka Nima Yooshij, Parviz Natel Khanlari, Nader Naderpour, Forough Farrokhzad, Mehdi Akhavan Saless, Sohrab Sepehri, Fereydoon Moshiri, Siavash Kasrai, Ahmad Shamlu, Hushang Ebtehaj, and Mohammad-Reza Shafiei Kadkani are considered to be the most famous, skilful, and professional. Though Nima Yooshij (1896–1960) is known as the Father of New Persian Poetry, aka Nimaii Poetry or "She'r-e Nimaii", according to a number of eminent and highly respected literary and poetry scholars Nader Naderpour is considered as the first Iranian poet who opened up exciting vistas of the new Persian poetry.
Document 3: Western Iranian languages: The Western Iranian languages are a branch of the Iranian languages, attested from the time of Old Persian (6th century BC) and Median.
Document 4: Iranian languages: It is possible that other distinct dialect groups were already in existence during this period. Good candidates are the hypothethical ancestor languages of Alanian/Scytho-Sarmatian subgroup of Scythian in the far northwest; and the hypothetical "Old Parthian" (the Old Iranian ancestor of Parthian) in the near northwest, where original *dw > *b (paralleling the development of *ćw).
Document 5: Iranian languages: Old Persian is the Old Iranian dialect as it was spoken in south-western Iran by the inhabitants of Parsa, who also gave their name to their region and language. Genuine Old Persian is best attested in one of the three languages of the Behistun inscription, composed circa 520 BC, and which is the last inscription (and only inscription of significant length) in which Old Persian is still grammatically correct. Later inscriptions are comparatively brief, and typically simply copies of words and phrases from earlier ones, often with grammatical errors, which suggests that by the 4th century BC the transition from Old Persian to Middle Persian was already far advanced, but efforts were still being made to retain an "old" quality for official proclamations.
Document 6: Nader Shah: Nader Shah (Persian: نادر شاه افشار ‎, translit. Nāder Šāh Afšār; also known as Nader Qoli Beyg نادر قلی بیگ or Tahmāsp Qoli Khan تهماسپ قلی خان) (August 1688 -- 19 June 1747) was one of the most powerful Iranian rulers in the history of that nation, ruling as Shah of Persia from 1736 to 1747 when he was assassinated during a rebellion. Because of his military genius as evidenced in numerous martial encounters throughout his campaigns, such as the battles of Herat, Mihmandust, Murche - Khort, Kirkuk, Yeghevard, Khyber Pass, Karnal and Kars, some historians have described him as the Napoleon of Persia or the Second Alexander. Nader Shah was an Iranian who belonged to the Turcoman Afshar tribe of Khorasan in northeastern Iran, which had supplied military power to the Safavid dynasty since the time of Shah Ismail I.
Document 7: Iranian languages: The multitude of Middle Iranian languages and peoples indicate that great linguistic diversity must have existed among the ancient speakers of Iranian languages. Of that variety of languages/dialects, direct evidence of only two have survived. These are:
Document 8: Iranian languages: Two of the earliest dialectal divisions among Iranian indeed happen to not follow the later division into Western and Eastern blocks. These concern the fate of the Proto-Indo-Iranian first-series palatal consonants, *ć and *dź:
Document 9: Iranian languages: What is known in Iranian linguistic history as the "Middle Iranian" era is thought to begin around the 4th century BCE lasting through the 9th century. Linguistically the Middle Iranian languages are conventionally classified into two main groups, Western and Eastern.
Document 10: Nader Mashayekhi: Nader Mashayekhi (; born November 26, 1958 in Tehran) is a Persian composer. From 2006 to July 2007 he was conductor of the Tehran Symphony Orchestra. He is the son of Jamshid Mashayekhi.
Document 11: Asadi Tusi: Abu Mansur Ali ibn Ahmad Asadi Tusi () was a Persian poet, linguist and author. He was born at the beginning of the 11th century in Tus, Iran, in the province of Khorasan, and died in the late 1080s in Tabriz. Asadi Tusi is considered an important Persian poet of the Iranian national epics. His best-known work is "Garshaspnameh", written in the style of the "Shahnameh".
Document 12: Massoud Nawabi: Massoud Nawabi (1954–2010; Persian: مسعود نوابی-; alternative spellings: Masood Nawabi) also known as Ustad Nawabi, was an Afghan poet, writer, Director as well as a cultural personality, founder of Educational Committee for Afghan Refugees (ECAR), Afghan Cultural Center, Ghulam Habib Nawabi, Chief Administrator of the Afghan Ibn-e-Sina University and Principle of Ariana Mahajir High School. Massoud Nawabi was the Son of Ghulam Habib Nawabi, who was the last of the great Persian Poet and among the first to introduce modern Dari poetry to Afghanistan.
Document 13: Iranian languages: In addition to Old Persian and Avestan, which are the only directly attested Old Iranian languages, all Middle Iranian languages must have had a predecessor "Old Iranian" form of that language, and thus can all be said to have had an (at least hypothetical) "Old" form. Such hypothetical Old Iranian languages include Carduchi (the hypothetical predecessor to Kurdish) and Old Parthian. Additionally, the existence of unattested languages can sometimes be inferred from the impact they had on neighbouring languages. Such transfer is known to have occurred for Old Persian, which has (what is called) a "Median" substrate in some of its vocabulary. Also, foreign references to languages can also provide a hint to the existence of otherwise unattested languages, for example through toponyms/ethnonyms or in the recording of vocabulary, as Herodotus did for what he called "Scythian".
Document 14: Shams Langeroodi: Mohammad Shams Langeroodi () (born November 17, 1950 in Langerood, Iran) is a contemporary Iranian poet, author and university lecturer. He has researched extensively on different periods of Persian poetry, most famous of which has resulted in An Analytic History of Persian Modern Poetry in four volumes. He is currently in the process of publishing his second novel.
Document 15: Shahnameh: The first to undertake the versification of the Pahlavi chronicle was Abu - Mansur Daqiqi, a contemporary of Ferdowsi, poet at the court of the Samanids, who came to a violent end after completing only 1,000 verses. These verses, which deal with the rise of the prophet Zoroaster, were afterward incorporated by Ferdowsi, with acknowledgment, in his own poem. The style of the Shahnameh shows characteristics of both written and oral literature. Some claim that Ferdowsi also used Zoroastrian nasks, such as the now - lost Chihrdad, as sources as well.
