शासि-वसि-घसीनां च

Thus अन्वशिषत्, अन्वशिषताम्, अन्वशिषन्, the Aorist of शास्; the च्लि is replaced by अङ् 3.1.56, and the आ changed to इ by 6.4.34. So also शिष्टः, शिष्टवान् ॥ From वस् we have उषितः, उषितवान्, उषित्वा ॥ The Samprasarana takes place by (VI. I. 15) as it belongs to yajadi class. From घस् we have जक्षतुः, जक्षुः in the Perfect. घस् is the substitute of अद् 2.4.40, the penultimate अ is elided by 6.4.98. So also अक्षन् in अक्षन्नमीमदन्त पितरः (Rig. I. 82. 2). This is the Aorist form of अद्, the घस् is substituted for अद् 2.4.37 the Aorist sign is elided by 2.4.80.

This sutra is made to cover cases not governed by the last sutra, namely, where the स् is not an adesa. Though the स् in घस् is the स् of a substitute, yet it is not governed by the preceding aphorism, because the word आदेशस्य there means 'the स् which is a substitute'. Here स् is not a substitute, but a portion of a substitute. The non-substitute घस् is not to be taken here : as it seldom occurs.

The word इण्कोः is understood here also. Therefore the rule would not apply to शास्ति, वसति and जघास ॥,
