Begamati zuban

Begamati zuban or Begamati bhasha (بیگماتی زبان; बेगमती भाषा; also written as begamati zubān, begamati zabān, begmati bhāsha) is a sociolect of Hindustani spoken by the noblewomen (begums) residing in seclusion (purdah) in royal forts and palaces in Delhi and some other Hindustani-speaking towns in India, primarily in the 19th century but not completely dying out until the 1970s. One of the main ways we know about the sociolect is through its representation in 19th century novels. It is not fully preserved, and what we know of it today is largely the result of its former documentation.
