Since the 19th century, it has been the most commonly used script for Sanskrit. Devanagari is used to write Standard Hindi, Marathi, Nepali along with Awadhi, Bodo, Bhojpuri, Gujari, Pahari, (Garhwali and Kumaoni), Konkani, Magahi, Maithili, Marwari, Bhili, Newar, Santhali, Tharu, and sometimes Sindhi, Dogri, Sherpa, Kashmiri and Punjabi. It was formerly used to write Gujarati. Because it is the standardised script for the Hindi language, Devanagari is one of the most used and adopted writing systems in the world. ~Wikipedia
