|Malayalam, Grantha, Vattezhuthu, Malayanma|
Kolezhuthu (கோலெழுத்து, കോലെഴുത്ത്) is one of the oldest writing systems in South India. It was mainly used to write Malayalam language  and Tamil language particularly during the former's infancy, along with Vatteluttu alphabet.
Kolezhuthu, which means line letters, in contrast with Vattezhuthu, which means circle letters, is considered by some to also have been known as Pallava-Chola script, which eventually evolved into the Tamil script that is used for the Tamil language.
