About Tamil script and Sanskrit.
In many Tamil books, magazines and newspapers, I have noticed the occurence of the following letters from Sanskrit: ja, occasionally sha(as in shivaa or gaNEsha), sha(as in vishNu or kirushNa), sa , ha, occasionally ksha(a combination of d+cha is used to write this sound) and sri. Is this a remanant of the old convention of using the Grantha alphabet to write Sanskrit words in Tamil? I heard somewhwere else on the forum that this convention was once used expecially in subjects the required the use of alot of Sanskrit words. Unfortunately, there are no examples of this old convention anywhere on Internet. I hope someone can shed more light on how these letters managed to be retained in modern Tamil usage.
