The later Indian grammarians, who did not belong to the Paninian school of grammar, have practically added nothing to the teachings of the muni-traya, i.e. Panini, Katyayana and Patanjali. Generally speaking, the later grammarians based their grammatical systems neither on the facts of the language as employed in the older or contemporary literature nor did they aim at adapting the rules of their predecessors to the changed conditions of the language. They were engaged almost exclusively in rearranging the rules of their predecessors and in changing the terminology and wording of those rules, amounting to economising syllables in most cases35 2. The Paninian System of Vyakarana 2.1. Panini (6th cent. B. C.) composed a grammar of Sanskrit language popularly known as Astadhyayi, a treatise consisting of eight (asta) chapters (adhyaya); it is also called astaka, astika, vrttisutra, mulasastra and sabdanusasana, and it comprises in all about four thousand (4,000) grammatical statements in extremely economised words (sutra). "These sutras are traditionally assigned to six types, viz., definitions (samjna), meta-rules (paribhasa), headings (adhikara), operational rules (vidhi), restrictions (niyama), extension rules (atidesa) and negation rules (nisedha)36. 2.2. As is very clear from the name itself, the Astadhyayi consists of eight chapters (adhyayas) further subdivided into quarter chapters (pada). The work begins with the sutra 'Atha Sabdanusasanam' and is immediately followed by a catalogue of sounds itself subdivided into fourteen (14) groups variously called the Pratyahara-sutras ("abbreviation formula"), siva-sutras, and Mahesvara-sutras, implying thereby that they are meant for formulating the necessary abbreviations of the basic sounds utilized in the Astadhyayi, or that these formula are bestowed to Panini by Siva or Mahesvara. Some scholars like Skold, Mangala Deva Sastri, Faddegon, Konow, etc., claim that the Siva-sutras were not set up by Panini, but by a predecessor. However, research into the relation between these sets of sounds and the rules of the Astadhyayi has brought out their intimate relation with each other and no serious student of Panini any longer holds the above view.
