After a neutral aṅga (stem), i is substituted for the endings (jas and śas) of Nominative 1st-Case and Accusative -2nd case.,
Thus कुण्डानि तिष्ठन्ति, कुण्डानि पश्य, दधिनी, मधूनि, त्रपूणि, जतूनि ॥ The augment न् is by 7.1.72. The word शस् in the sutra being read along with जस् denotes the Accusative Plural ending शस् and not the Taddhita affix शस् 5.4.43; as कुण्डशो ददाति, वनशः प्रविशति ॥,
