The Assamese Alphabet/অসমীয়া বৰ্ণমালা
(Part 2)
(Read Part 1 here)
The Assamese alphabet or Assamese script, is a writing system of the Assamese language. This script was also used in Assam and nearby regions for Sanskrit as well as other languages such as Bodo (now Devanagari), Khasi (now Roman), Mising (now Roman), Jaintia (now Roman) etc. It evolved from Kamarupi script.
The present standard is identical to the Bengali alphabet except for two letters, ৰ (ro) and ৱ (vo); and the letter ক্ষ (khya) has evolved into an individual consonant by itself with its own phonetic quality whereas in the Bengali alphabet it is a conjugate of two letters.
