Commentary
The affix शप् comes after a root when a सार्वधातुक follows, signifies the agent.
In active voice, शप् is employed in the conjugational tenses. This affix, which is technically called a विकरण comes after roots of the भू class and after compound roots formed by सन् &c. 3.1.32. The indicatory श makes it a सार्वधातुक affix by (III.4. II3), the प् indicates that the vowel has anudatta accent 3.1.4. As भू + शप् + तिप् = भू + अ + ति = भो + अ + ति = भवति. 7.3.84. So also पचति.
