Sagir Ahmed สกิรอาห์เมด Aavinash Chaliha Assamese language was derived from kutila style prevalent in northern India roughly around 6th century, which is phonetically complete unlike Bengali. Another difference in the triangular and angular shaped symbols , causing a major difference with nagari scripts.

@nekibah48501023 Aavinash Chaliha Languages are not same as scripts. Did you mean Assamese script?
Yeah it derived from that. Which later developed into several different scripts.
