अहन्

Thus अहोभ्याम्, अहोभिः ॥ The sutra exhibits the form अहन् without the elision of न्, in order to indicate that there is not elision of न् ॥ As दीर्घाहो, निदाघः, हे दीर्घाहोऽत्रेति ॥ See Vartika to 8.2.7. The न् of अहन् is not changed to र् in the sutra by 8.2.69, because it is intended to show the word-form अहन् ॥ The Nominal stem is Pada in the above examples by 1.4.17.

Vart:- Before the words रूप, रात्रि and रथन्तर, the न् of अहन् is changed to र् ॥ As अहोरूपम्, अहोरात्रः, अहोरथन्तरं साम ॥ This is an exception to 8.2.69. Others say, that this र् change takes place universally before all words beginning with र; as अहो रम्यम्, अहो रत्नानि ॥,
