Śrauta is a Sanskrit word that means "belonging to śruti", that is, anything based on the Vedas of Hinduism. It is an adjective and prefix for texts, ceremonies or person associated with śruti. The term, for example, refers to Brahmins who specialise in the śruti corpus of texts, and Śrauta Brahmin traditions in modern times can be seen in Kerala and Coastal Andhra.
