Sadhu bhasha

Sadhu bhasha was used in official documents and legal papers during the colonial period; however, it is mostly obsolete in the present day.

Notable among them was Iswar Chandra Vidyasagar, who standardised the Bengali alphabet and paved the path for literary works.

The colloquial usage of Bengali consisted mostly of its Prakrit base as well as indigenous (deshi), Persian and Arabic words embedded into the vocabulary.

This in turn increased the commonality in Bengali vocabulary with other Indo-Aryan languages, such as Hindi which has also consciously replaced Persian and Arabic elements with Sanskrit Tatsama, a process which separated it form the Khariboli source and Urdu.

The newspaper Anandabazar Patrika uses Sadhu Bhasha on their editorial column, partially, even today.
