What is the name of the special kind of Sanskrit in Rigveda used in composing hymns dedicated to Agni, the god of fire?

Vedic Sanskrit

The Rigveda contains two verses dedicated to Agni, the god of fire, often linked to the sacrificial fire used to make offerings and connect with other deities. The verses implore Agni, the wise and generous giver, to accept their sacrifice and bestow abundant food and wealth through the act of sacrificing.

Furthermore, they pray for the gift of nourishment, symbolized by the wonderful cow, and for the blessing of having a son to continue their lineage.

These verses were crafted in Vedic Sanskrit, a unique form of the language. They were orally transmitted and taught to members of priestly families.
