चूर्णादीन्यप्राणिषष्ठ्याः

The words चूर्ण etc. in a तत्-पुरुष समास have acute accent (उदात्त) on the first syllable when preceding word ends in a Genitive 6th-Case and does not denote a living being.
Thus मुद्गचू꣡र्णम्, ससूरचू꣡र्णम्, but मत्स्यचू꣡र्णम् where the first term is a living being, and परमचू꣡र्णम् where it is not Genitive. Another reading of the sutra is चूर्णादीन्यप्राण्युपग्रहात्, the word उपग्रह being the ancient name of षष्ठी given by old Grammarians.

1 चूर्ण, 2 करिव, 3 करिप, 4 शाकिन, 5 शाकट, 6 द्राक्षा, 7 तूस्त, 8 कुन्दुम (कुन्दम), 9 दलप, 10 चमसी, 11 चक्कन (चकन चक्वन), 12 चौल ॥

The word चूर्ण is derived from the root चूरी दाहे (Divadi 50) with the affix क्त; करिव and करिप are formed with the upapada करि and the verbs वा 'to go' and पा 'to protect' respectively, and the affix क (करिणं वाति = करिव) 3.2.3; शक with the affix इनण् added diversely (Unadi II.56); शक with अटच (Unadi IV. 81) gives शकट; this with अण् (तद्वहति) gives शाकट; द्राक् क्षरति = द्राक्षा (Prishodaradi); तुस् (शब्दे) with क्त gives तूस्त the penultimate being lengthened; the word कुन्दु is formed by the affix क्विप् added to the root दु with the upapada कु (कुन्दुनोति कुत्सितं वा दुनोति) the augment मुस् being added to कु ॥ कुन्दुं मिमीते = कुन्दुमः ॥ दल with the affix कपन् gives दलपः, चम with असच् forms चमस, then is added ङीष्; चक्कन is formed by अच् 3.1.134 added to कन् and reduplication. चोलस्यापत्यं = चौलः ॥
