Replace /ik with /yaN before vowels.

That is to say, replace i I u U R RR L इ ई उ ऊ ऋ ॠ ऌ with y v r l य्व्र्ल्.

Examples —

**madhu मधु n + **atra अत्र → !**madhvatra मध्वत्र "the honey is here"

**buddhi- बुद्धिॱ f + /TA → buddhyA बुद्ध्या "by intellect"

**pitR- पितृॱ + /TA → !**pitrA पित्रा "with Father"

**RSi- ऋषिॱ + /os → !**RSyos ऋष्योस् "of two seers"

**vRkI वृकी + **azvam अश्वम् + anudravati अनुद्रवति → vRkyazvamanudravati वृक्यश्वमनुद्रवति "she-wolf runs after horse"

This rule is overriden by akassavarN... q.v.

This sUtra is an example of the uses of cases in sUtras. The nounbase /ik carries sixth (/Gas) here to mean "replace an /ik", and /ac carries seventh (/Gi) to mean "before an /ac".

How can you be sure that the rule akassavarN... is stronger that this one?

If this one were weaker, then akassavarN... would apply to a / A + a / A only. And then most of the akassavarN... rule would be useless. /pANini did not do "useless".
