Who wrote 'Ashtadhyayi', the earliest comprehensive grammar of Sanskrit?

Correct Answer: Panini

Subject: history

Panini
Sushruta
Charaka
Vyasa

Explanation: Panini (c. 4th century BCE) wrote the 'Ashtadhyayi' (Eight Chapters) — a grammatical treatise of 3,976 sutras (rules) that systematically describes Sanskrit grammar. It is considered one of the greatest intellectual achievements of any ancient civilization — so complete that Sanskrit grammar is essentially unchanged since Panini. He was from Shalatula (near Taxila). Later grammarians: Katyayana (added Vartikas) and Patanjali (wrote Mahabhashya). Sushruta wrote Sushruta Samhita (surgery). Charaka wrote Charaka Samhita (medicine). Vyasa is traditionally attributed with the Mahabharata and compiling the Vedas.
