Commentary
मुम् is the augment of सत्य and अगद when the word कार follows.
As सत्यंकारः = सत्यंकरोति or सत्यस्यकारः ॥ So also अगदंकारः ॥
Vart:- So also of अस्तु, as अस्तुंकारः ॥
Vart:- So also in Vedas, of भक्ष before कारः -e. g. भक्षंकार, in secular language भक्षकारः ॥
Vart:- Of धेनु before भव्या, e.g. धेनुंभव्या ॥
Vart:- Of लोक before पृण, e.g. लोकंपृणा ॥
Vart:- Of अनभ्याश before इत्य as अनभ्याशमित्यः ॥
Vart:- Of भ्राष्ट्र and अग्नि, before इन्धः, as भ्राष्ट्रामिन्धः, अग्निमिन्धः ॥
Vart:- A word before गिल takes मुम् augment, unless it is also गिल e.g. तिमिङ्गिलः, but गिलगिलः ॥
Vart:- So also before गिलगिल, e.g. तिमिङ्गिलगिलः ॥
Vart:- Of उष्ण and भद्र before करण, e. g. उष्णं करणं, भद्रंकरणं ॥
Vart:- पुत्रड् is optionally the substitute of दुहितृ when the words सूत, उग्र, राज, भोज, and मेरु precede it e. g. सूतपुत्री or सूतदुहिता, उग्रपुत्री or उग्रदुहिता, राजपुत्री or राजदुहिता, भोजपुत्री or भोजदुहिता, मेरुपुत्री or मेरुदुहिता ॥ Some read पुत्र in the Sarangaravadi class 4.1.73, and then this word has its feminine पुत्री ॥ This is seen in other places also, e.g. शैलपुत्री ॥
