After a word ending in the gotra affix -- [[4.1.95]], there is elision of luk of the yuvan affix, when the gotra of the people called prācya 'Eastern' is denoted.,
पान्नागर + इञ् = पान्नागारिः 'the Gotra descendent of Pannagara'; after this the Yuvan affix फक 4.1.101 is elided by the present rule, and so पान्नागारिः is both the father and the son. So मान्यरैषणिः father and son. The word प्राचाम् here qualifies the word Gotra understood and does not show that it is an optional rule in the opinion of Eastern Grammarians. When the Gotra of Prachyas is not denoted, there is no elision. Thus दाक्षिः and दाक्षायणः 'son of Dakshi.',
