ekAco bazo bhaS jhaS-antasya s;dhvoH

एकाचो बशो भष्झषन्तस्य स्ध्वोः ONPANINI 82037

Replace with an aspirated the initial b ब् g ग् d द् D ड् of an /ekAc root that ends in a jh झ् bh भ् gh घ् Dh ढ् dh ध् that is padafinal or before s स् dhv ध्व्.

I call this one "the throwback rule", because it appears to make an aspiration jump back, like this —

budh बुध् → bhud भुद्, as in **bhutsISTa भुत्सीष्ट
dah दह् → dhag धग्, as in **adhAkSIt अधाक्षीत्
duh दुह् → dhug धुग्, as in !**kAmadhuk कामधुक् (from **kAmaduh- कामदुह् + /su)

Example when padafinal —

duh- दुह् (as in **kAmaduh- कामदुह्) + /su
→ duh दुह् by halGyAbbhyodIrgh...
→ dugh दुघ् by <<<<< dAderdhAtorgh...
→ dhugh धुघ् by this rule
→ dhug धुग् by jhalAJjazonte >>
→ !**dhuk धुक् normalizing if before pause

Example before s स् —

budh बुध् + soft liG /ta
→ budh बुध् + **sISTa सीष्ट
→ **bhutsISTa भुत्सीष्ट "may he wake up"

Example before dhvam ध्वम् —

budh बुध् + /luG /dhvam
→ budh बुध् + /sic + /dhvam by cliluGi and clessic
→ (there is no gbS before /sic because it is /kit by liGsicAvAtm...)
→ abudh अबुध् + s स् + /dhvam by luGlaGlRGkSvaD...
→ abudh अबुध् + /dhvam by <12 dhica
→ abhudh अभुध् + /dhvam by this rule
→ abhud अभुद् + /dhvam by jhalAJjazjhaz...
→ !**abhuddhvam अभुद्ध्वम् "you''' awoke"

Why "before s स् dhv ध्व्"?

No bh भ् here —

budh बुध् + /tavya → !**boddhavya- बोद्धव्यॱ

budh बुध् + /kta → **buddha- बुद्धॱ
