Commentary

A guttural is not substituted for the final ज् of अज् and व्रज् before an affix having an indicatory ध् and before ण्यत्।
This is an exception to 7.3.52. Thus समाजः, उदाजः, परिव्राजः and परिव्राज्यम् ॥ There is no example of अज् with the affix ण्यत्, because by 2.4.56, वी replaces अज् before all ardhadhatuka affixes except घञ् and अप् ॥ The च of the sutra implies that the rule applies to other roots also not mentioned, as वाजः, वाज्यम् from वज् ॥
