Malayalam is a Dravidian language spoken in the Indian state of Kerala and the union territories of Lakshadweep and Puducherry by the Malayali people. It is one of 22 scheduled languages of India. Malayalam was designated a "Classical Language of India" in 2013.

The word Malayalam originated from the words mala, meaning 'mountain', and alam, meaning 'region' or '-ship' (as in "township"); Malayalam thus translates directly as 'the mountain region'. The term Malabar was used as an alternative term for Malayalam in foreign trade circles to denote the southwestern coast of the Indian peninsula, which also means The land of hills.[24][25][26][27] The term originally referred to the western hilly land of the Chera dynasty (later Zamorins and the Kingdom of Cochin), Kingdom of Ezhimala (later Kolathunadu), and Ay kingdom (later Travancore), and only later became the name of its language.[28] The language Malayalam was alternatively called Alealum, Malayalani, Malayali, Malabari, Malean, Maliyad, Mallealle, and Kerala Bhasha until the early 19th century CE.[29][30][31]

The earliest extant literary works in the regional language of present-day Kerala probably date back to as early as the 12th century. At that time the language was differentiated by the name Kerala Bhasha. The distinctive 'Malayalam' named identity of this language appears to have come into existence only around the 16th century, when it was known as "Malayayma" or "Malayanma"; the words were also used to refer to the script and the region.[32] According to Duarte Barbosa, a Portuguese visitor who visited Kerala in the early 16th century CE, the people in the southwestern Malabar coast of India from Kumbla in north to Kanyakumari in south had a unique language, which was called "Maliama" by them.[33][34]

Prior to this period, the people of Kerala usually referred to their language as 'Tamil', and both terms overlapped into the colonial period.
