The affixes ṣṭhan and ṣṭhac come respectively after the words kusīda and daśaikādaśa when the sense is 'he gives for a mean motive'.,
The word कुसीद means 'interest'. The lending of ten (दश) on a condition that the borrower will pay eleven (एकादश) after a month is called दशैकादश ॥ This sutra debars ठक् ॥ The difference between the two affixes ष्ठन् and ष्ठच् is in the accent 6.1.197 and 6.1.163 Thus कुसीद + ष्ठन् = कु꣡सीदकः fem. कुसीदकी꣡ 6.1.41. So दशैकादशिकः꣡ fem की꣡ ॥,
