The affix ghañ comes after the roots 1. pad 'to pace' 2. ruj 'to pain 3. viś 'to enter' 4. spṛś 'to touch'.,
The anuvritti of 'future' does not extend to this sutra. The affixes hereinafter taught come in all the tenses.
As पद + घञ् = पादः 'foot'; रुज् + घञ् = रोगः 'disease'; so, वेशः 'entrance'.
Vart:- The verb स्पृश् takes घञ् when the sense is that of 'distress'; as स्पर्शः 'disease' or 'warmth'. The word स्पर्श meaning 'touch' is formed by adding the affix अच्, under rule 3.1.134; as स्पर्शो देवदत्तः । There is difference in accent between these two words.,
