Simplified Tamil script or Reformed Tamil script refers to several governmental reforms to the Tamil script.
In 1978, the Government of Tamil Nadu reformed certain syllables of the modern Tamil script with view to simplify the script. It aimed to standardize non-standard ligatures of ஆ ā, ஒ o, ஓ ō and ஐ ai syllables.
Furthermore, only 13 out of 15 of the proposed simplifications were successful as people continued to use ஐ ai instead of the proposed அய் ay and ஔ au instead of the proposed அவ் av.
