Hindi (in the broad sense) is a dialect continuum of the Indic language family in the northern plains of India, bounded on the northwest and west by Punjabi, Sindhi, Gujarati and Marathi; on the east by Bengali; and on the north by Nepali. As defined by the 1991 Indian census, Hindi covers a number of Central, East-Central, Eastern, and Northern Zone languages, including the Bihari languages, the Rajasthani languages, and the Pahari languages excepting Dogri and Nepali. Since the dialects form a continuum, there are no sharp boundaries, and they are conventionally divided more simply into a Western and an Eastern group.
