The affix khac comes after the verb kṛ 'to make' when the words megha 'cloud' arti 'misfortune' and bhaya 'fear' are in composition as objects.,
As मेघङ्करः 'producing clouds'; ऋर्तिकरः 'giving pain'; भयङ्करः 'frightful'.
Vart:- The tadanta vidhi applies in the case of upapadas like भय. &c. This is an exception to the vartika under (1. 1. 72.) by which, in the case of affixes, tadanta-vidhi was prohibited. Thus we have अभयङ्करः 'who causes security'.,
