Sanskrit is today commonly written in the Devanāgarī script which is used for writing other Indian languages like Hindi, Marathi, Nepali etc. However there are many other Indian scripts which have been used to write Sanskrit in the last 2500 years.
The International Alphabet of Sanskrit Transliteration (IAST) is a popular system which uses the Roman (English) alphabets for writing and reading Sanskrit, mainly used by those who may not be equally familiar with Devanāgarī. The IAST system is widely used by western scholars and students of Sanskrit in the last 150 years.
