Commentary
In a द्वन्द compound of the Names of Divinities, both the members retain their original accent.
Thus, इ꣡न्द्रासोमौ꣡, इ꣡न्द्राव꣡रुणौ, इ꣡न्द्राबृ꣡हस्पती ॥ The word इन्द्र has acute on the first (by nipatana), सोम is formed by मन् (Unadi I.140), and has acute on the first 6.1.197, वरुण is formed by उनन् (Unadi III.53) and by 6.1.197 has acute on the first. बृ꣡हस्प꣡ति has two acutes by 6.2.140, and Indra-Brihaspati has three acutes. Why do we say "names of divinities"? Observe प्लक्षन्यग्रोधौ ॥ Why do we say 'a Dvandva'? Observe अग्निष्टोमः ॥
