Definition: a short gloss on the Aṣṭādhyāyī of Pāṇini in the l2th century by Puruṣottamadeva, a reputed scholar belonging to the Eastern school of grammarians which flourished in Bengal and Behar in the 10th, 11th and 12th centuries, The gloss is very useful for beginners and it has given a clear explanation of the different sūtras without going into difficult niceties and discussions. The treatise does not comment upon Vedic portions or rules referring to Vedic Language because, as the legend goes, king Lakṣmaṇa Sena, for whom the gloss was written, was not qualified to understand Vedic Language; cf. वैदिकभाषानर्हत्वात् Com. on Bhāṣāvṛtti by Sṛṣṭidhara. There is a popular evaluation of the Bhāṣāvṛtti given by the author himself in the stanza"काशिकाभागवृत्त्योश्चेत्सिद्धान्तं बोद्धुमस्ति धीः ! तदा विचिन्त्यतां भ्रातर्भाषावृत्तिरियं मम"at the end of his treatise; for details see पुरुषोत्तमदेव.
