Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.

Commentary

The final नश् at the end of a word is optionally changed to guttural.
The word पदस्य is understood here also. As सा वै जीवनडाहुतिः (Maitr. Samhita. I.4.13): or सा वै जीवनगाहुतिः ॥ According to Pro. Bohtlingk this latter form is not found in the Samhita.

Here the root नश has taken क्विप् in denoting 'condition or state'; by considering it as belonging to संपदादि class.

जीवस्य नाशः = जीवनक् or जीवनट् ॥ The gutturalisation optionally debars the ष change of 8.2.36. When the ष change takes place, this ष is changed to ट् by 8.2.39 and 8.4.56.
