Definition: name popularly given to the Sūtrapāṭha of Pāṇini consisting of eight books (adhyāyas) containing in all 3981 Sūtras,as found in the traditional recital, current at the time of the authors of the Kāśika. Out of these 398l Sūtras, seven are found given as Vārtikas in the Mahābhāṣya and two are found in Gaṇapāṭha.The author of the Mahābhāṣya has commented upon only 1228 of these 3981 sūtras. Originally there were a very few differences of readings also, as observed by Patañjali (see Mbh on I.4.1); but the text was fixed by Patañjali which, with a few additions made by the authors of the Kāśika,as observed above, has traditionally come down to the present day. The Aṣṭādhyāyī is believed to be one of the six Vedāṅga works which are committed to memory by the reciters of Ṛgveda. The text of the Aṣṭādhyāyī is recited without accents. The word अष्टाध्यायी was current in Patañjali's time; cf. शिष्टज्ञानार्था अष्टाध्यायी M. Bh. on VI. 3.109.
