A dhātupāṭha is a list of Sanskrit verbal roots. Different grammatical schools in the Sanskrit grammatical tradition (vyākaraṇa) have different dhātupāṭhas: e.g. the Pāṇinian Dhātupāṭha of the Pāṇinian school and the Kātantra Dhātupāṭha of the Kātantra school. The Pāṇinian Dhātupāṭha, as published in Böhtlingk’s Aṣṭādhyāyī edition (1st Indian edition 1998), contains verbal roots equipped with markers (anubandha), accents, and meaning entries. The Pāṇinian Dhātupāṭha is an indispensable ancillary text to the Aṣṭādhyāyī, the knowledge of which the latter assumes, and without which the teachings in the latter cannot be fully understood.
