Maharashtri, Sinhala, Sauraseni and Niya (Gandhari), emerge in the Middle Indo-Aryan stage in two versions—archaic and more formalized—that may be placed in early and middle substages of the 600 BCE–1000 CE period. Two literary Indo-Aryan languages can be traced to the late Middle Indo-Aryan stage and these are Apabhramsa and Elu (a literary form of Sinhalese). Numerous North, Central, Eastern and Western Indian languages, such as Hindi, Gujarati, Sindhi, Punjabi, Kashmiri, Nepali, Braj, Awadhi, Bengali, Assamese, Oriya, Marathi, and others belong to the New Indo-Aryan stage. There is an extensive overlap in the vocabulary, phonetics and other aspects of these New Indo-Aryan languages with Sanskrit, but it is neither universal nor identical across the languages. They likely emerged from a synthesis of the ancient Sanskrit language traditions and an admixture of various regional dialects. Each language has some unique and regionally creative aspects, with unclear origins. Prakrit languages do have a grammatical structure, but like Vedic Sanskrit, it is far less rigorous than Classical Sanskrit. While the roots of all Prakrit languages may be in Vedic Sanskrit and ultimately the Proto-Indo-Aryan language, their structural details vary from Classical Sanskrit. It is generally accepted by scholars and widely believed in India that the modern Indo-Aryan languages – such as Bengali, Gujarati, Hindi, and Punjabi – are descendants of the Sanskrit language. Sanskrit, states Burjor Avari, can be described as "the mother language of almost all the languages of north India". Geographic distribution The Sanskrit language's historic presence is attested across a wide geography beyond South Asia. Inscriptions and literary evidence suggests that Sanskrit language was already being adopted in Southeast Asia and Central Asia in the 1st millennium CE, through monks, religious pilgrims and merchants. South Asia has been the geographic range of the largest collection of the ancient and pre-18th-century Sanskrit manuscripts and inscriptions. Beyond ancient India, significant collections of Sanskrit manuscripts and inscriptions have been found in China (particularly the Tibetan monasteries), Myanmar, Indonesia, Cambodia, Laos, Vietnam, Thailand, and Malaysia. Sanskrit inscriptions, manuscripts or its remnants, including some of the oldest known Sanskrit written texts, have been discovered in dry high deserts and mountainous terrains such as in Nepal, Tibet, Afghanistan, Mongolia, Uzbekistan, Turkmenistan, Tajikistan, and Kazakhstan. Some Sanskrit texts and inscriptions have also been discovered in Korea and Japan. Official status In India, Sanskrit is among the 22 official languages of India in the Eighth Schedule to the
