Commentary
The first member in a बहुव्रीहि समास , before the words 1. उदर 2. अश्व and 3. इषु , gets acute accent (उदात्त) on the final syllable when the compound denotes a Name.
Thus वृको꣡दरः, दामो꣡दरः, हर्य॑श्वः, यौवना꣡श्वः, सुवर्णपुङ्खे꣡षुः and महेषुः꣡ ॥ This sutra is also an exception to 6.2.1 by which the first term would have retained its original accent. The word वृ꣡क has acute on the first by Phit II .7. The word दा꣡म is formed by मनिन् affix (Unadi IV. 145) and is first acute; ह꣡रि is also first acute as formed by इन् (Unadi IV. 118). The word यौवन if considered as an underived primitive, has acute on the first by Phit II.19. If it be considered as derived from युवन् with the affix अण् then it is already end-acute and would retain its accent even by 6.2.1. The first Bahuvrihi word सुवर्ण has acute on the final by 6.2.172, the second Bahuvrihi compound सुवर्णपुंखाः has acute on र्ण by 6.2.1, the third Bahuvrihi with इषु gets accent on ख ॥ The word महत is end-acute by 5.2.38. Its mention here appears redundant.
