________________ liv pointed out conflicts between Paninian rules and the Unadisutras. The most acceptable view in accord with the evidence appears to Cardona to be that not all the rules which appear in the Unadi treatises we have can be Panini's, as is clear from conflicts between the works. Further, Panini's referring to Unadi affixes does not mean he himself compiled a list of such affixes. The only certainty is that Panini knew of Unadi affixes and accepted some of the derivations involving them 153. The Un-adi affixes headed by the affix 'Un' are similar to'Krt' affixes of Panini, giving derivation mostly of such words as are not derived by rules of Panini. No particular sense such as agent, object etc. is mentioned in connection with these affixes, but as Panini has stated in his sutra "Tabhyam anyatronadayah' (3.4.75), the various Unadi affixes are applied to the various roots as prescribed in any Karaka sense, except the Sampradana and the Apadana; in other words, any one of the senses such as agent, object, instrument and abode, is assigned to the Unadi affix as suits the meaning of the word. Patanjali who apparently ascribes the collection to Sakatayana, as seen from an interesting passage of the Maha-bhasya on the sutra 'Unadayo bahulam' (3.3.1), has given a very interesting discussion about these Unadi affixes and stated on the strength of the Vartika 'Tatronadi-pratisedhah', that these affixes and the words given in the Unadi collection should not be considered as genuinely derived. Since the derivation is not a very systematic and logically correct one; for practical purpose, the words derived by the application of the affixes Un and others should be looked upon as underived (avyutpannani pratipadikani) 154. While sarvavarman, the author of the Katantra did not compose his Unadi-sutras, it was Durga who added them to this system, although some hold that these sutras proper are composed by Indragomin and adopted in the Katantra. It has 399 Sutras and 255 Pratyayas 155. Panini has treated his Unadi from 3.3.1 onwards, and it refers to the Unadi-patha containing 748 Sutras divided into five Padas, ascribed to sakatayana. Candra takes up the Unadis from 1.3.1 onwards and it refers to the Candra Unadi-patha consisting of 328 Sutras divided into three Padas 15h. Jainendra starts its Unadis from 2.2.167 (JM) and 2.2.182 (JS). So far, the independent Unadi-patha of this school has not come to light, and of the Unadi-sutras quoted by Abhayanandin in his Mahavrtti some are similar to those of the Pancapadi, while others differ, and still others are such that they utilise the Sanjnas peculiar to Jainendra, thus indicating the possibility of an independent Unadi-patha of the school'57. Modern Jain Sakatayana treats his Unadis from the Sutra 4.3.280. By this he
