Replace the i इ u उ of the /abhyAsa with iy इय् uv उव् before non-/savarNa vowel.

This can only apply if the root starts with a vowel.

The reduplication happens only after the /liT is added (/paratvAt).

uS उष् "burn" + /liT /tip
→ uS उष् + /Nal
→ oS ओष् + /Nal by gbS
→ u उ + oS ओष् + /Nal by several rules
→ !**uvoSa उवोष by this rule

iS इष् → **iyeSa इयेष

yaj यज् → **iyAja इयाज

vac वच् → **uvAca उवाच

But before /savarNa vowel, akassavarN... works normally —

uS उष् + /liT /jhi → u उ + uS उष् + /us → !**USus ऊषुस् "they inhabited"

u उ + uc उच् + /us → **Ucus ऊचुस् "they said"

u उ + uc उच् + /atus → **Ucatus ऊचतुस् "both said"
