सुधातुः अकङ् च
Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
सुधातुः → अकङ्
Replace sudhātuḥ with akaṅ. Inherited words (anuvṛtti) may add further conditions.
Commentary
The affix इञ् is placed after the word सुधातृ in denoting the descendant and the ऋ of सुधातृ is replaced by the substitute अकङ् before this affix.
Thus सुधातुरपत्यम् = सौधातकिः 'the descendant of Sudhatri.'
Vart:- The substitute अकङ् replaces the finals of व्यास, वरुड, निषाद, चण्डाल and बिम्ब when the Patronymic इञ् is to be added. Thus, वैयासकिः, वारुडकिः नैषादकिः, चाण्डालकिः, बैम्बकिः ॥
