Commentary
A compound beginning with श्वन् and followed by the तद्धित affix इञ् is not governed by the prohibition nor takes the augment taught in द्वारादीनां च 7.3.4.
Thus the descendant of श्वभस्त्र is श्वाभस्त्रिः, so also श्वादंष्ट्रिः ॥ The word श्वन् is included in the list of Dvaradi words 7.3.4., the present sutra implies that the rule 7.3.4 applies not only to those words, but to compounds beginning with those words.
Vart:- This rule applies when any Taddhita affix beginning with इ follows; as श्वगणेन चरति = श्वागणिकः, श्वायूथिकः 4.4.11.
The prohibition applies, when other Taddhita affixes follow such a word ending with इञ् (an affix beginning with इ) : as from श्वाभस्त्रि we have श्वाभस्त्रम् (श्वाभस्त्रेरिदं) ॥
