Commentary
The affix अञ् comes in the sense of 'its law' after a प्रातिपदिक (Nominal Stem) ending ऋ।
This debars ठक् ॥ Thus पोतु र्धर्म्यम् = पौत्रम् 'the office of a Potri.' औद्गात्रम् 'the office or duties of an Udgatri'. Padamanjari gives the example of हौत्रम् = होतु र्धर्म्यम् under this sutra, though the word होतृ occurs in the list given in the preceding sutra. The Hotri of the preceding sutra means a Ritvik, here it means an invoker.
Vart:- So also after the word नरः As नरस्य धर्म्या = नारी ॥
Vart:- So also after the word विशसितृ, the इट् affix being elided. Thus विशसितृ + अञ् = वैशस्त्रम् ॥
Vart:- So also after the word विभाजयितृ, its णि affix also being elided. Thus विभाजयितृ + अञ् = वैभाजित्रम् ॥
