Replace ārdhadhātukasya valādeḥ with iṭ. Inherited words (anuvṛtti) may add further conditions.
Commentary
An आर्धधातुक affix -- आर्द्धधातुकं शेषः 3.4.114 etc., beginning with a consonant (except य) gets the augment इट् (in these rules).
Thus लविता, लवितुम्, लवितव्यम्, पविता, पवितुम्, पवितव्यम् ॥ Why 'ardhadhatuka'? Observe आस्ते, वस्ते ॥ The niyama rule of 7.2.76 ordaining इट् augment to sarvadhatuka affixes of Rudadi verbs, would prevent इट् augment before sarvadhatuka affixes when coming after other roots. The employment of ardhadhatuka here can be dispensed with. Why before affixes beginning with a वल्-consonant? Observe लव्यम्, पव्यम्, लवनीयम्, पवनीयम् ॥ Though the anuvritti of इट् was understood here, its repetition is for the sake of preventing the prohibition of the foregoing sutras like 7.2.8.
