The affix aṇ -- prāgdīvyato'ṇ [[4.1.83]] when it is added to a word which denotes either the object of a battle or the warrior of a battle fought for that object or by that warrior as a leader.,
The phrase सोऽस्य is understood here; showing that the word in construction to which the affix is to be added must be in the first case: and must be the name of the \object\ प्रयोजनः, or of the \warrior\ योद्धृ ॥ The whole word so formed must denote a 'battle'. Therefore, the word संग्राम gives the meaning of the affix.
This भद्रा प्रयोजनमस्य संग्रामस्य = भाद्रः \A battle fought for Bhadra\. So also सौभाद्रः \a battle fought to gain Subhadra\. Similarly अहिमाला योद्धारोऽस्य संग्रामस्य = आहिमालः 'battle led by Ahimala warriors' So also स्यान्दनाश्वः, भारतः ॥
Why do we say \in the sense of a battle?\ Observe सुभद्रा प्रयोजनमस्य दानस्य 'Subhadra is the object of this gift'. Here no affix is added. Why do we say 'after a word denoting an object or a warrior'? Observe, सुभद्रा प्रेक्षिकाऽस्य संग्रामस्य ।,
