प्राग्-इवात् कः

Properly speaking क extends only upto 5.3.86. Thus in the sutra अज्ञाते 5.3.73, the word क must be supplied to complete the sense. As अश्वकः, गर्दभकः ॥ This affix क does not come after finite verbs (तिङन्त), but the affix अकच् 5.3.71 comes after such verbs. In other words, the phrase तिङश्च 5.3.56, should be connected, by way of anuvritti, with the next sutra, and not with this.,
