When Buddhism emerged as a new religion people started speaking languages much simpler than Sanskrit. These were known as the Prakrit. In the pre-Gupta period the inscriptions especially the series of Ashoka's edicts are in Prakrit. Prakrits were simpler than Sanskrit in respect of both sound and grammar. One of the early Prakrit of considerable importance was Pali which became the language of one sect of the Buddhists.
Tamil is the oldest of Dravidian languages with a literature dating back to the earliest centauries after the beginning of the Christian era. These languages form an independent group with a distinctive character. From the very early times Tamil was affected by Sanskrit. Early Tamil literature contains relatively few words from Sanskrit and they were adapted to the Tamil phonetic system.
