Commentary
A monosyllabic word ending in any vowel other than अ when followed by a word formed by a खित् affix receives the augment अम् which is added in the same way as the affix अम् of the Accusative -2nd case singular.
The word अम् is to be repeated here thus, इच एकाचोऽम्, अम्प्रत्ययवच्च ॥ Thus गांमन्यः, स्त्रींमन्यः, or स्त्रियंमन्यः, श्रियंमन्यः, भ्रुवंमन्यः ॥ By force of the atidesa अम्प्रत्ययवत्, the changes produced by the Accusative ending are caused by this augment also : viz: the substitution of long आ, the substitution of a vowel homogenous with the first, the guna, the substitutes इयङ् and उवङ् As आ-गां मन्यः 6.1.93; पूर्वसवर्ण as स्त्रींमन्यः 6.1.107; guna, as, - नरंमन्यः 7.3.110 and इयङ् and उवङ्, as श्रियंमन्यः, भ्रुवंमन्यः 6.4.81 &c)). Why do we say ending in a vowel other than अ (इच्)? Observe त्वन्मन्यः ॥ Why do we say 'a monosyllable'? Observe लेखाभ्रुं मन्याः ॥
The affix अम् is elided after a Neuter noun 7.1.23, therefore, will this अम् also be elided when श्री is treated as Neuter? As श्रियमात्मानं मन्यते ब्राह्मणकुलं = श्रियंमन्यम् or श्रिमन्यम्? The second is the valid form according to Patanjali.
