'ī and ū': Objection: the continuation of the vowel u is superfluous, since in 'the two women or the two fruits, those two sit' (striyau phale vā amū āsāte), it is established by the preceding rule itself, because even though the change to m is suspended (asiddha), it ends in e. To this he says: 'rāmakṛṣṇau' etc. The idea is that in the masculine it is not established by the previous rule, because it ends in au. But with respect to the rule 'adaso māt' (pā. sū. 1.1.12), the substitution of m-plus-ū and m-plus-ī are not suspended, because of the force of its formulation. 'The vowel e also': thus the idea is that the mention of 'after m' (māt) serves the purpose of conveying the non-continuation of the vowel e. / Here this should be considered: why was it not phrased simply as 'īdūtsaptamyarthe pragṛhyam', 'adasaḥ', 'ecca dvivacanam'? For in this way, there would be no need for the mention of ī and ūt in the preceding rule, nor for the mention of māt in the present rule. Nor would there be the trouble of partial continuation (ekadeśānuvṛtti).
