He instituted Tamil alphabet reforms and his reasons are as follows:

In writings and publications of 70 or 80 years ago, the vowel ‘ee’ (i:), indicated today as ‘ ¼ ‘, was a cursive and looped representation of the short form, ‘ ¬ ‘ (i). In stone inscriptions of 400 or 500 years ago, many Tamil letters are found in other shapes. The older and the more divine a language and its letters are said to be, they, in truth, need reform.

Just as some compound characters have separate signs to indicate their length as in ‘ æè ‘ , ‘ îæ ‘ (ka: , ke:), why should not other compound characters like ‘ æ¨ ‘ , ‘ æ© ‘ , ‘ Æ ‘ , ‘ Ô ‘ (ki, ki:,ku, ku:) (indicated integrally as of now), also have separate signs? This indeed requires consideration.

Changing the shape of letters, creating new symbols and adding new letters and similarly, dropping those that are redundant, are quite essential.The glory and excellence of a language and its script depend on how easily they can be understood or learnt and on nothing else.
