Commentary
A word in the Dative -4th Case as the first member retains its accent when the second member expresses that which is suited to become the former.
Thus यू꣡पदारु, कुण्डल꣡हिरण्यम् ॥ The word यूप् has accent on the first syllable, as it is formed by प (Unadi III.27) treated as a नित् (Unadi III.26). The word कुण्डल is formed by कल affix which is treated as चित् (Unadi I.108) and has acute on the final. So also र꣡थदारु, वल्लीहिरण्यम् ॥ Ratha is first-acute formed by kthan affix (Unadi II.2). Valli has acute on the final formed by ङीष् affix. 4.1.41 Why do we say 'it being suited to the first'? Observe कुबेरबलिः ॥ This accent applies when the second member denoting the material is modified into the first by workmanship. The composition takes place by 2.1.36.
