अदसो मात्

In the pronoun अदस्, the dual termination in ई, ऊ or ए will be pragrihya by force of the last sūtra, but the present sûtra makes this addition, that in the case of अदस्, all terminations ending in ई, ऊ or ए and preceded by म, of whatever number they may be, will be pragrihya. As a matter of fact, there are only two such terminations satisfying the above conditions namely अमी and अमू. The rule may therefore be put in the following words of Dr. Max Muller:- \The terminations of अमी and अमू nom. plur. masc. and nom. dual of the pronoun अदस् are pragrihya.\ As अमी अश्वाः \Those horses\, and अमू आसते. There is no example of the word adas ending in ए.

Why do we say \of the word adas\? The letters ई, ऊ, ए following after the म् of any other word will not be pragrihya. As शमी+अत्र = शम्यत्र \this sami tree.\

Why do we say \after the letter म्\? Because in the example अमुके+अत्र = अमुकेऽत्र, \those here,\ the ए, preceded not by म् but by the क of अकच् 5.3.71 is not pragrihya, which it would have been by the influence of sūtra II, which includes ए as well as ई and ऊ, and from which the word dual is not supplied here, else this rule would be useless.,
