Sanskrit is the classical language of Indian and the liturgical language of Hinduism, Buddhism, and Jainism. It is also one of the 22 official languages of India. The name Sanskrit means "refined", "consecrated" and "sanctified". It has always been regarded as the 'high' language and used mainly for religious and scientific discourse.
Vedic Sanskrit, the pre-Classical form of the language and the liturgical language of the Vedic religion, is one of the earliest attested members of the Indo-European language family. The oldest known text in Sanskrit, the Rigveda, a collection of over a thousand Hindu hymns, composed during the 2nd millennium BC.
Today Sanskrit is used mainly in Hindu religious rituals as a ceremonial language for hymns and mantras. Efforts are also being made to revive Sanskrit as an everyday spoken language in the village of Mattur near Shimoga in Karnataka. A modern form of Sanskrit is one of the 17 official home languages in India.
Since the late 19th century, Sanskrit has been written mostly with the Devanāgarī alphabet. However it has also been written with all the other alphabets of India, except Gurmukhi and Tamil, and with other alphabets such as Thai and Tibetan. The Bhaiksuki, Grantha, Sharda and Siddham alphabets are used only for Sanskrit.
Since the late 18th century, Sanskrit has also been written with the Latin alphabet. The most commonly used system is the International Alphabet of Sanskrit Transliteration (IAST), which was been the standard for academic work since 1912.
