<human>: Answer by taking a quote from the following article:

The Malayali people or Keralite people (also spelt Malayalee, Malayalam script: mlyaalli and keerlliiy[?]) are an Indian ethnic group originating from the present-day state of Kerala, located in South India. They are identified as native speakers of the Malayalam language, which is classified as part of the Dravidian family of languages. As they primarily live in Kerala, the word Keralite is used as an alternative to Malayali. According to the Indian census of 2011, there are approximately 33 million Malayalis in Kerala, making up 96.7% of the total population of the state.

Malayalam is the language spoken by the Malayalis. Malayalam is derived from old Tamil and Sanskrit in the 6th century. For cultural purposes Malayalam and Sanskrit formed a language known as Manipravalam, where both languages were used in an alternating style. Malayalam is the only among the major Dravidian languages without diglossia. This means, that the Malayalam which is spoken does not differ from the written variant. Malayalam is written using the Malayalam script.  Malayalam literature is ancient in origin. The oldest literature works in Malayalam, distinct from the Tamil tradition, is dated between the 9th century and 11th century. Malayalam literature includes the 14th century Niranam poets (Madhava Panikkar, Sankara Panikkar and Rama Panikkar), whose works mark the dawn of both modern Malayalam language and indigenous Keralite poetry. The Triumvirate of poets (Kavithrayam: Kumaran Asan, Vallathol Narayana Menon and Ulloor S. Parameswara Iyer) are recognized for moving Keralite poetry away from archaic sophistry and metaphysics and towards a more lyrical mode. In 19th century Chavara Kuriakose Elias, the founder of Carmelites of Mary Immaculate and Congregation of Mother of Carmel congregations, contribute different streams in the Malayalam Literature. All his works are written between 1829 and 1870. Chavara's contribution  to Malayalam literature includes, Chronicles, Poems - athmanuthapam (compunction of the soul), Maranaveettil Paduvanulla Pana (Poem to sing in the bereaved house) and Anasthasiayude Rakthasakshyam - and other Literary works . In the second half of the 20th century, Jnanpith awardees like G. Sankara Kurup, S. K. Pottekkatt, Thakazhi Sivasankara Pillai and M. T. Vasudevan Nair and non Jnanpith awardees like Vaikom Muhammad Basheer have made valuable contributions to the Malayalam literature.  Later, such Keralite writers as O. V. Vijayan, Kamaladas, M. Mukundan, and Booker Prize winner Arundhati Roy, whose 1996 semi-autobiographical bestseller The God of Small Things is set in the Kottayam town of Ayemenem, have gained international recognition.  Kerala remains a fascinating riddle for the Indian diaspora, especially the younger generations - World Malayali Council with its sister organisation, International Institute for Scientific and Academic Collaboration (IISAC) has come out with a comprehensive book on Kerala titled 'Introduction to Kerala Studies,' specially intended for the Malayali diaspora across the globe. J.V. Vilanilam, former Vice-Chancellor of the University of Kerala; Sunny Luke, medical scientist and former professor of Medical Biotechnology at Adelphi University, New York; and Antony Palackal, professor of Sociology at the Loyola College of Social Sciences in Thiruvananthapuram, have edited the book, besides making other contributions to it.
