दीर्घो ऽकितः ONPANINI 74083

(Replace a अ) of a non-/kit (/abhyAsa) with A आ (before /yaG or /yaGluk).

So, here we have an abhyAsa pa प that is not /kit —

pac पच् + /yaG + /laG /ta
→ pa प + pac पच् + ya य + /ta
→ **pApacyate पापच्यते "he cooks and cooks"

But we do not have lengthening here, because the /abhyAsa is /kit —

yaMyamyate यंयम्यते

yaMyamIti यंयमीति — !! i think this I ई is from yaGovA but i'm not sure

When is the /abhyAsa a /kit?

When it receives augments nIk नीक्, muk मुक् by the following sUtras, like nugatonun... >>.
