[2] The devices employed in Insha include verbal puns, and tricks, riddles, and a mannered, elegant style of writing.
[4] In the classical Persian literature, the most representative type of "Insha is identified as "Rasail", meaning "letters".
[5] Further categories exist due to the nature of the letters and the relationship and comparative status of the addressee and the writer.
for instance if the writer is the ruler of a kingdom, then the Insha issuing from him could be categorized into farman, manshur or fathnama, depending on the nature of its contents.
Munshaat -i- Namakin is one of the largest collections of Insha writings, which is dated from the early Mughal period.
