Chapter 1.4 Grantha letters

The Grantham script was developed in Southern India in the Pallava period during the 5th century CE. There are a few that are still used in Tamil. These are mainly used to spell words of Sanskrit origin. They combine with the vowels just like the other consonants do. With the “Thani Tamil” (pure Tamil) movement the Grantham words are written using the closest Tamil alphabets. For example, ஜ is a nasal pronunciation of ச, so the Tamil ச is used in the place of the Grantham letter ஜ

The Grantham letters are:

ஜ், ஷ், ஸ், ஹ், க்ஷ் and ஸ்ரீ. These combine with the Tamil vowels just like the other consonants.
