Commentary
The affix श्यन् comes after a root of the दिवादि class when a सार्वधातुक affix denoting the agent follows.
This debars शप्. The servile न of श्यन् is for the sake of accent 6.1.197, showing that the udatta accent falls on the radical verb and not on the affix; and the indicatory श makes the affix sarvadhatuka; as दिव् + श्यन् + तिप् = दीव् + य + ति 7.2.77 = दीव्यति; so also सीव्यति. The Divadi verbs belong to the Fourth conjugation.
