A corresponding ja, ba, ga, ḍa or da is substituted for all consonants (with the exception of semi-vowels and nasals) at the end of a word.,
As वाग् अत्र, श्वलिड् अत्र, अग्निचिद् अत्र, त्रिष्टुब् अत्र ॥ The word श्वलिट् is formed by changing the ह् of लिह् to ढ first, and then changing this ढ to ड, a jas-letter.
The word अन्त 'at the end' is used in the sutra to indicate that the anuvritti of झलि ceases. Thus वस्ता, वस्तुम्, वस्तव्यम् ॥
The exceptions to this have been given in 8.2.30 &c, and 8.2.66. At an avasana or Pause, a चर् consonant may be substituted for a झल् by 8.4.56.,
