According to the opinion of Eastern Grammarians the affixes aḍac and vuc also come after a human name beginning with the word upa,
The च shows that the former affixes also come. The sense of the affixes are the same as above viz. compassion or courtesy. Thus from the word उपेन्द्रदत्त, we have, 1. उपेन्द्रदत्तकः (kan), उपिकः (thach), 3, उपिलः (ilach), 4. उपियः (ghan), 5. उपकः (vuch), 6. उपडः (adach). The shortened forms are by 5.3.83. In diminutives, the forms are generally shortened. The word प्राचां is used as a sign of respect (pujartha), for the word वा was understood in the aphorism by anuvritti from 5.3.78.,
