The Katantra (Sanskrit: कातन्त्र; IAST: Kātantra) is a treatise on Sanskrit grammar (Vyakarana) attributed to Sharvavarman living at the time of the Satavahana dynasty.[1]
It is a simplified and abridged version of Pāṇini's Aṣṭādhyāyī and divided into the chapters Sandhi, Nāmni Catuṣṭaya and Ākhyāta.
The terms Kālāpa, Kālāpaka and Kālāpa-vyākaraṇasūtra refer to either the Katantra or a different version of it.[2]
Arthur Coke Burnell compared the arrangement of the Katantra to those of the Aindra school and the Tolkāppiyam.[3]
