Example.
Acording to the rest of the grammar, we should logically expect a certain word to have this form —
Iks ईक्स् + /zap + /muk + /zAnac + /su → IkSamAnaH "while he was looking around"
However, rule aTku अट्कु forbids saying that. Why? The S ष् in IkS ईक्ष् makes the tongue curl up, and the tongue is still bit curled up while we say a अ, m म्, A आ. This means that when we get to the n न्, the tongue is still a bit curled up, and at that point saying Na ण is easier than saying na न. So what we actually say is —
!**IkSamANaH ईक्षमाणः "while he was looking around"
