इटः अत्
Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
इटः → अत्
Replace iṭaḥ with at. Inherited words (anuvṛtti) may add further conditions.
Commentary
The short अ is the substitute of इ of the आत्मनेपद first person singular in the Potential and Benedictive.
Thus पचेय, यजेय, कृषीय, हृषीय ।
Q.-- In the sutra, the word अत् is used, and the final त् belongs to the विभक्ति, therefore by rule (1.3. 4), this त् is not indicatory; why is it made so ?
A.-- This त is not any portion or member of the substitute; it is added to अ merely for the sake of euphony.
The इट् refers to the आत्मनेपद affix of the first person singular; and not to the augment इट् on the strength of the maxim अर्थवद्ग्रहणे नानर्थकस्य । A combination of letters capable of expressing a meaning denotes, whenever it is employed in grammar, that combination of letters in so far as it possesses that meaning, but it does not denote the same combination of letters void of a meaning.
