Which one of the following statements about the grammarian Katyayana is correct?

Correct — C, He belonged to a period between Panini and Patanjali. The order is fixed by what each of the three wrote, not by any dated record, and that is what makes it reliable. Panini composed the Ashtadhyayi in the fifth or fourth century BCE. Katyayana then wrote varttikas — short critical notes examining Panini's rules, correcting some, restricting others, adding what he thought had been left out. Patanjali's Mahabhashya, of about the second century BCE, is a commentary on Panini's sutras and on Katyayana's varttikas together, discussing both. A commentator who explains and adjudicates between two earlier authorities must come after both of them, and a critic who annotates a text must come after that text. So the sequence Panini, then Katyayana, then Patanjali follows from the literature itself. These three are known in the tradition as the muni traya, the three sages of Sanskrit grammar, and their order is exactly the order in which they are named.

• (a)He was a contemporary of Panini. — A commentator's notes on a work do not appear alongside it. Katyayana's varttikas examine the Ashtadhyayi as a finished and already authoritative text.
• (b)He was a contemporary of Patanjali. — Patanjali's Mahabhashya discusses Katyayana's varttikas as inherited material to be weighed, sometimes disagreeing with them. That is the relation of a later commentator to an earlier one.
• (d)He belonged to a period later than both Panini and Patanjali. — The reverse of the true order. If Katyayana were later than Patanjali, the Mahabhashya could not be commenting on his varttikas.

Sanskrit grammar has a three-stage foundation. Panini's Ashtadhyayi, in just under four thousand sutras, generates correct Sanskrit forms by ordered rules. Katyayana's varttikas are critical notes on those sutras — where a rule over-applies, where it needs a further condition, where a form is left unaccounted for. Patanjali's Mahabhashya, the 'great commentary', takes up Panini and Katyayana together and argues the cases out at length, often in dialogue form. Together the three are the muni traya, and later Sanskrit grammar is built on all three rather than on Panini alone.

This item is really about a method: dating by textual dependence. Very little in early Indian intellectual history can be dated by a record, but relative order can often be established with confidence, because a commentary presupposes its text. Applied here, the chain is airtight — varttikas presuppose the Ashtadhyayi, and the Mahabhashya presupposes both. The same reasoning is worth carrying to other questions in the paper: it is what places the Ashtadhyayi earliest among four Sanskrit texts in question 33, since a work that had already attracted a major commentary by the second century BCE must itself be considerably older. When an option set offers 'contemporary of X' against 'between X and Y', ask what each author wrote about whom, and the answer usually falls out without any dates at all.

• Panini composed the Ashtadhyayi in the fifth or fourth century BCE.
• Katyayana wrote varttikas — critical notes examining, correcting and supplementing Panini's rules.
• Patanjali's Mahabhashya, of about the second century BCE, comments on both Panini's sutras and Katyayana's varttikas.
• The order Panini → Katyayana → Patanjali is established by textual dependence, not by dated records.
• The three together are called the muni traya, the three sages of Sanskrit grammar.
• Patanjali the grammarian is traditionally distinguished from the Patanjali of the Yoga Sutras.

• Treating the three grammarians as roughly contemporary because they are named together as the muni traya.
• Confusing Patanjali the grammarian with the author of the Yoga Sutras.
• Expecting absolute dates where only relative order is secure — the question asks for position, not a century.

As a relative-chronology item on the three grammarians, or as an author-to-work match across Ashtadhyayi, varttikas and Mahabhashya.

• practice — not a real PYQ

  The varttikas of Katyayana are best described as

  • (a)an independent grammar of Sanskrit
  • (b)critical notes on Panini's sutras
  • (c)a commentary on the Mahabhashya
  • (d)a lexicon of Sanskrit synonyms

  Answer(b) critical notes on Panini's sutras — examining, restricting and supplementing the rules of the Ashtadhyayi.

• practice — not a real PYQ

  The three grammarians known collectively as the muni traya are

  • (a)Panini, Katyayana and Patanjali
  • (b)Panini, Bhartrihari and Patanjali
  • (c)Katyayana, Bharata and Patanjali
  • (d)Panini, Amarasimha and Katyayana

  Answer(a) Panini, Katyayana and Patanjali — named in that order, which is also their chronological order.
