After the verbs as 'to throw', vac 'to speak' and khyā 'to speak', aṅ is the substitute of cli , when luṅ (Aorist) follows signifying an agent.,
वच् may be either the root, or the substitute of ब्रू 2.4.53 and so also ख्या may be the root, or the substitute of चक्ष् 2.4.54. The root अस् belonging to the दिवादि or the Fourth conjugation, falls under the subdivision पुषादि, and therefore it would have taken अङ् in the Parasmaipada by rule (III. I. 55). The repetition is to indicate that it takes अङ्, in the Atamanepada also; as पर्यास्थत 7.4.17, अवोचत् and आख्यत्. In the Passive, we have पर्यासिषाताम्.,
