अपरिमाण-बिस्त-आचित-कम्बल्येभ्यो न तद्धितलुकि

This debars 'nip' which otherwise would have presented itself by virtue of the last sutra. The words बिस्तः 'a weight of gold equal to 80 Raktikas', आचितम् 'a measure of 10 cart-loads or 80,000 tolahs'; and कम्बल्यः 'a measure', all denote measure; and are the only words expressing measure to which this rule applies. The word परिमाण means 'measure', as distinguished from संख्या 'a Numeral', See 5.1.19, &c.

Thus पञ्चाश्व is a Dvigu compound, meaning 'purchased for five horses.' Here the Taddhita affix ठञ् 5.1.37 giving the sense of 'purchased with' has been elided by 5.1.28. This compound does not end in a word denoting parimana techincally so called or a measure. The feminine of this word will not be formed by ङीप् but by टाप्, thus, पञ्चश्वा 'a female purchased for five horses'.

The words denoting 'time' or 'number' are not words denoting 'measure' as understood in this sutra by the word 'parimana'. Thus, द्विवर्षा, 'a two years old female child', त्रिवर्षा 'a three years old female child' (V. 2. 37 Vart.) So also द्विशता 'a female purchased for two hundreds', similarly त्रिशता ॥ So also with the words बिस्त &c. As द्विबिस्ता 'purchased for two bistas', त्रिबिस्ता, द्व्याचिता, त्र्याचिता, द्विकम्बल्या, and त्रिकम्बल्या, &c.

Why do we say 'not ending in a word denoting a Parimana or a 'measure'? Observe द्व्याढकी, त्र्याढकी \a female purchased for two or three adhaka\. Here adhaka means a measure equal to 7 Ib. II oz. avoir.

Why do we say 'when a Taddhita affix is elided'? In 'Samahara Dvigu' compounds, the affix 'nip' will apply. Thus पञ्चाश्वी 'an aggregate of five horses', so also दशाश्वी ॥,
