Sanskrit is the main holy language of Hinduism and Mahayana Buddhism. It dates back to as early as 1500 BCE. When written out, Sanskrit is believed to look like a combination of Hebrew, Japanese, and Chinese characters.

Sanskrit is still used in Hindu religious ceremonies, mainly in hymns and prayers. With a mere 14,000 native speakers, Sanskrit is one of the world’s quickly vanishing languages. However, there is a modern version of the ancient language being revived in Karnataka, in southwest India.
