Definition - What does Devanagari mean?
Devanagari (also known as Nagari) script is an alphasyllabary (meaning a combination of consonants and vowels) alphabet used in classical Sanskrit texts. It is a system of writing that uses cursory symbols with square outlines and round shapes. This style of writing is written and read from left to right.

Yogapedia explains Devanagari
One of the oldest surviving Sanskrit texts using Devanagari was written by Patanjali, who also wrote the Yoga Sutras. Devanagari script is artful: it uses sharp, straight lines as well as curves to represent 47 characters, and uses no capital letters. The script is thought to be used for more than 120 languages, and is an alphabet used in both Nepal and India.
Devanagari is a compound word in Sanskrit with deva meaning “deity” and nagari meaning “city” or “urban." This suggests that the script itself is both divine and worldly.
