तृणह इम्

As तृणेढि, तृणेक्षि, तृणेह्मि, अतृणेट् ॥ In the last example though the affix vanishes altogether, yet it produces its effect. Why beginning with a consonant? Observe तृणहानि ॥ Why a पित् affix? Observe तृण्ढः with तस् ॥ The stem तृणह is formed from the root तृह् (Rudhadi) with the vikarana श्नम्, and is so exhibited in the sutra in order to indicate that the augment इम् is added after the vikarana श्नम् has been added, and that the root तृह् of Tudadi class is not to be taken.

The above forms are thus derived:-

तृह् + श्नम् + तिप् = तृणह् + इम् + ति = तृणइह + ति = तृणेह् + ति (VI. I. 87) = तृणेढ् + ति 8.2.31 = तृणेढ् + धि 8.2.40 = तृणेढ् + ढि 8.4.41 = तृणेढि with the elision of one ढ 8.3.13. The form तृणेक्षि is similarly formed by 8.2.41, the ढ् being changed to क before सि of सिप् ॥ अतृणेट् is the लङ् 2nd and 3rd Person Singular.,
