Commentary
The affix अच् comes in the sense of मतुप् after the words अर्श etc.
Thus अर्शोसि अस्य विद्यन्ते = अर्शसः उरसः &c. ॥ After a word denoting a member of the body comes the affix अच्, when defect is meant. As खञ्जः पादोस्यास्ति = खञ्जः, काणः ॥ So also after words denoting color, as शुक्लोऽस्यास्ति = शुक्लः पटः ॥
1 अर्शस्, 2 उरस्, 3 तुन्द, 4 चतुर, 5 पलित, 6 जटा, 7 घटा, 8 घाटा, 9 अघ (अभ्र), 10 कर्दम, 11 अम्ल (आम), 12 लवण, 13 स्वाङ्गाद्धीनात्, 14 वर्णात् आकृतिगण ॥
