Vedic Sanskrit
In this layer of Vedic literature, the archaic Vedic Sanskrit verb system has been abandoned, and a prototype of pre-Panini Vedic Sanskrit structure emerges. The "Yajñagāthās" texts provide a probable link between Vedic Sanskrit, Classical Sanskrit and languages of the Epics. Complex meters such as "Anuṣṭubh" and rules of Sanskrit prosody had been or were being innovated by this time, but parts of the Brāhmaṇa layers show the language is still close to Vedic Sanskrit.
