whereas the latter is used formally and poetically, being of Persian origin. If a word is of Persian or Arabic origin, the level of speech is considered to be more formal and grander. Similarly, if Persian or Arabic grammar constructs, such as the izafat, are used in Urdu, the level of speech is also considered more formal and grander. If a word is inherited from Sanskrit, the level of speech is considered more colloquial and personal. Writing system Urdu is written right-to left in an extension of the Persian alphabet, which is itself an extension of the Arabic alphabet. Urdu is associated with the Nastaʿlīq style of Persian calligraphy, whereas Arabic is generally written in the Naskh or Ruq'ah styles. Nasta’liq is notoriously difficult to typeset, so Urdu newspapers were hand-written by masters of calligraphy, known as kātib or khush-nawīs, until the late 1980s. One handwritten Urdu newspaper, The Musalman, is still published daily in Chennai. A highly Persianised and technical form of Urdu was the lingua franca of the law courts of the British administration in Bengal and the North-West Provinces & Oudh. Until the late 19th century, all proceedings and court transactions in this register of Urdu were written officially in the Persian script. In 1880, Sir Ashley Eden, the Lieutenant-Governor of Bengal in colonial India abolished the use of the Persian alphabet in the law courts of Bengal and ordered the exclusive use of Kaithi, a popular script used for both Urdu and Hindi; in the Bihar Province, the court language was Urdu written in the Kaithi script. Kaithi's association with Urdu and Hindi was ultimately eliminated by the political contest between these languages and their scripts, in which the Persian script was definitively linked to Urdu. More recently in India, Urdu speakers have adopted Devanagari for publishing Urdu periodicals and have innovated new strategies to mark Urdu in Devanagari as distinct from Hindi in Devanagari. Such publishers have introduced new orthographic features into Devanagari for the purpose of representing the Perso-Arabic etymology of Urdu words. One example is the use of अ (Devanagari a) with vowel signs to mimic contexts of (‘ain), in violation of Hindi orthographic rules. For Urdu publishers, the use of Devanagari gives them a greater audience, whereas the orthographic changes help them preserve a distinct identity of Urdu. Some poets from Bengal, namely Qazi Nazrul Islam, have historically used the Bengali script
