Hindi is the official and main link language of India. Its homeland is mainly in the north of India, but it is spoken and widely understood in all urban centers of India. It is written in the Devanagri script, which is phonetic and, unlike English, is pronounced as it is written. Hindi is a direct descendant of Sanskrit through Prakrit and Apabhramsha. It has been influenced and enriched by Dravidian, Turkish, Farsi, Arabic, Portugese and English. It is a very expressive language. In poetry and songs, it can convey emotions using simple and gentle words. It can also be used for exact and rational reasoning.
