form of Malayalam. During the 16th century CE, Thunchaththu Ezhuthachan from the Kingdom of Tanur and Poonthanam Nambudiri from the Kingdom of Valluvanad followed the new trend initiated by Cherussery in their poems. The Adhyathmaramayanam Kilippattu and Mahabharatham Kilippattu written by Ezhuthachan and Jnanappana written by Poonthanam are also included in the earliest form of Modern Malayalam. It is Thunchaththu Ezhuthachan who is also credited with the development of Malayalam script into the current form through the intermixing and modification of the erstwhile scripts of Vatteluttu, Kolezhuthu, and Grantha script, which were used to write the inscriptions and literary works of Old and Middle Malayalam. He further eliminated excess and unnecessary letters from the modified script. Hence, Ezhuthachan is also known as The Father of modern Malayalam. The development of modern Malayalam script was also heavily influenced by the Tigalari script, which was used to write Sanskrit, due to the influence of Tuluva Brahmins in Kerala. The language used in the Arabi Malayalam works of 16th–17th century CE is a mixture of Modern Malayalam and Arabic. They follow the syntax of modern Malayalam, though written in a modified form of Arabic script, which is known as Arabi Malayalam script. P. Shangunny Menon ascribes the authorship of the medieval work Keralolpathi, which describes the Parashurama legend and the departure of the final Cheraman Perumal king to Mecca, to Thunchaththu Ramanujan Ezhuthachan. Kunchan Nambiar introduced a new literary form called Thullal, and Unnayi Variyar introduced reforms in Attakkatha literature. The printing, prose literature, and Malayalam journalism, developed after the latter-half of 18th century CE. Modern literary movements in Malayalam literature began in the late 19th century with the rise of the famous Modern Triumvirate consisting of Kumaran Asan, Ulloor S. Parameswara Iyer and Vallathol Narayana Menon. In the second half of the 20th century, Jnanpith winning poets and writers like G. Sankara Kurup, S. K. Pottekkatt, Thakazhi Sivasankara Pillai, M. T. Vasudevan Nair, O. N. V. Kurup, and Akkitham Achuthan Namboothiri, had made valuable contributions to the modern Malayalam literature. Later, writers like O. V. Vijayan, Kamaladas, M. Mukundan, Arundhati Roy, Vaikom Muhammed Basheer, have gained international recognition. Malayalam has also borrowed a lot of its words from various foreign languages, mainly from the Semitic languages including Arabic, and the European languages including Dutch and Portuguese, due to the long heritage of Indian Ocean trade and the Portuguese-Dutch colonisation of the Malabar
