Language is the medium through which human beings communicate using words, whether written or spoken. In India, there are more than 200 types of languages. Indian Union recognizes languages in two main groups viz., (i) Indo-Eurasian; and (ii) Dravida. Dravidian languages are Tamil, Telugu, Kannada and Malayalam. Malayalam is the official language of Kerala. There is no authoritative history of the origin of Malayalam language. It is said that the word Malayalam is derived from the words Mala, which means mountain and alam, which means land. Scholars are of opinion that the language is derived from Sanskrit. Leelthilakom, one of the grammatical works says that the Malayalam is the sister language of Tamil. Another version is that the language is originated from the primitive form of Sanskrit. Some experts opined that the language is a mixture of Tamil and Sanskrit. One of the oldest records says that Malayalam is considered as an independent language from 9th century AD onwards. A.R.Rajaraja Varma, the famous Malayalam scholar had divided the history of Malayalam language into three stages. According to him it came out as an independent language only in 825 A.D. The first stage is from 825 A.D. to 1325 A.D. The second and third stages commenced from 1325 A.D., and 1625 A.D. respectively. In the first stage, it was closely related with Tamil. In the second stage it was related with Sanskrit also giving birth to a new literary style known as Manipravalam. In the 16th century, Thunchath Ramanujan Ezhuthachan transformed and standardised the Malayalam to its present form. Till then, the script used to write Malayalam was vattezhuthu, kolezethu, etc. The new alphabet and script, which was introduced by Thunchath Ramanujan Ezhuthachan is known as Grandhaksharam.
