Devanagari (i/ NAH-gər-ee; देवनागरी, IAST: Devanāgarī, Sanskrit pronunciation: [deːʋɐˈnaːɡɐɽiː]), also called Nagari (Nāgarī, नागरी), is a left-to-right abugida (alphasyllabary), based on the ancient Brāhmī script, used in the Indian subcontinent. It was developed in ancient India from the 1st to the 4th century CE, and was in regular use by the 7th century CE. The Devanagari script, composed of 47 primary characters including 14 vowels and 33 consonants, is one of the most adopted writing systems in the world, being used for over 120 languages. The ancient Nagari script for Sanskrit had two additional consonantal characters.
The orthography of this script reflects the pronunciation of the language. Unlike the Latin alphabet, the script has no concept of letter case. It is written from left to right, has a strong preference for symmetrical rounded shapes within squared outlines, and is recognisable by a horizontal line that runs along the top of full letters. In a cursory look, the Devanagari script appears different from other Indic scripts such as Bengali, Odia, or Gurmukhi, but a closer examination reveals they are very similar except for angles and structural emphasis.
Devanagari is a compound of "deva" देव and "nāgarī" नागरी.Deva meaning "heavenly or divine", and is also one of the terms for a deity in Hinduism,Nagri comes from नगर (nagar), which means abode or city. Hence, Devanagari denotes from the abode of divinity or deities.
