Malayalam first appeared in writing in the vazhappalli inscription which dates from about 830 AD. In the early thirteenth century the Malayalam script began to develop from a script known as vattezhuthu (round writing), a descendant of the Brahmi script.
As a result of the difficulties of printing Malayalam, a simplified or reformed version of the script was introduced during the 1970s and 1980s. The main change involved writing consonants and diacritics separately rather than as complex characters. These changes are not applied consistently applied so the modern script is often mixture of traditional and simplified characteres
Malayalam is also regularly written with a version of the Arabic script by Muslims in Singapore and Malaysia, and occasionally by Muslims in Kerala.
