Санскрит

Group Indic (with Hindi, Marathi etc.), Old Indic (with Vedic and Sanskrit)
Geography One of the main Old Indic languages, Sanskrit is not the direct descendant of Vedic, as some may suppose. If Vedic was used only as a dialect of North-Western India, Sanskrit was born in the north, in the Gang valley, and was used at the time when Vedic still existed. Sanskrit early became the language of the literature and fell out of use as a colloquial tongue. It was proclaimed a divine language in India, and all classical works in science, verse or history were written only in this language.
