Koleluttu
Koleḻuttŭ was a syllabic script historically employed in Kerala, south India, for writing the Malayalam language.
Kolezhuthu developed from the Vattezhuthu (script) during the post-medieval Chera period in Kerala. It was used by certain Keralite communities, such as Muslims and Christians, until as late as the 18th century AD.
The term Kolezhuthu is likely derived from the distinctive type of stylus traditionally used in its inscription. In present-day Malayalam, kōl refers to a stylus or an elongated stick-like object, while eḻuttŭ denotes 'written form'.
