Burhan-i Qati

'[The] Conclusive Proof')[1] is a Persian dictionary compiled during the 17th century by Muhammad Husayn bin Khalaf Tabrizi.

He settled in the Deccan region of the Indian subcontinent and served in the court of Abdullah Qutb Shah for some time.

The dictionary notably contains many non-Persian words from several Iranian languages such as Avestan, Khwarezmian, Sogdian, Sistani, Gilaki, and Tabari.

[1] The Burhan-i Qati became very famous following its completion due to its wide range of words and compounds, the convenience of its alphabetical ordering, and its collation of the material in other dictionaries.

[3] Towards the end of his life, famed poet Mirza Ghalib wrote a criticism of the Burhan-i Qati, titled 'Qati-i Burhan', which initiated a storm of controversy.
