The participial affixes optionally take the iṭ augment after roots having an indicatory ā when the affixes have an Impersonal sense or denote the beginning of an action.,
Thus मिन्नमनेन or मेदितमनेन, प्रमिन्नः, प्रमेदितः ॥ The Saunagas optionally make the Nishtha set after the root शक्, when the affix has a Passive significance even, as शकितो घटः कर्त्तुम् or शक्तोः घटः कर्त्तुम् ॥ Not so, when the affix has Impersonal force, as शक्तमनेन् ॥ The root अस् 'to throw' (अस्यति), is followed by सेट् Nishtha, when the sense is Impersonal: as असितमनेन; but not when the beginning of action is meant, as अस्तः काण्डः ॥,
