Definition: a very distinguished Grammarian who lived in the seventh century A. D. He was a senior contemporary of the authors of the Kasika, who have mentioned his famous work viz. The Vakyapadiya in the Kasika. cf. शब्दार्थसंबन्धोयं प्रकरणम् | वाक्यपदीयम् Kas. on P. IV.3.88. His Vyakarana work"the Vakyapadiya"has occupied a very prominent position in Grammatical Literature. The work is divided into three sections known by the name 'Kanda' and it has discussed so thoroughly the problem of the relation of word to its sense that subsequent grammarians have looked upon his view as an authority. The work is well-known for expounding also the Philosophy of Grammar. His another work"the Mahabhasya-Dipika"is a scholarly commentary on Patanjali's Mahabhasya. The Commentary is not published as yet, and its solitary manuscript is very carelessly written. Nothing is known about the birth-place or nationality of Bhartrhari. It is also doubtful whether he was the same person as king Bhartrhari who wrote the 'Satakatraya'.
