Pan-Indian Orthographic Alphabet

The Pan-Indian Orthographic script was invented by Srijon Sadhukhan from Mumbai in India. The script is based on the Latin alphabet, and is used to write languages spoken in the Indian Subcontinent, including countries like India, Pakistan, Bangladesh, Sri Lanka, Nepal and Afghanistan, and belonging to language families such as Indo-Aryan, Indo-Iranian and Dravidian. This script has also been adapted specifically to write various dialects of the Arabic language as well.

There has been a necessity for a suitable alphabet for a long time in India. Multilingual people often find it difficult to learn two or more scripts at a time. Therefore, due to the influence of English, people often discard the use of the native alphabets like Devanagari, Bengali, Tamil, Telegu, Urdu etc. Often the thought that Muslims in India generally use the Arabic alphabet is, in reality, not the same.

Srijon Sadhukhan invented his alphabet to better suit the phonology of various Indian languages within a pronounciation-based, common writing system. Different pronounciations are symbolized by a single letter. This script can be easily used to write Modern Standard Hindi-Urdu (Hindustani), Sanskrit and Modern Standard Bengali (Kolkata standard), and three related Aryan languages with much distinct phonological differences.
