see
覩 centers on the act of seeing or looking at something directly.
覩 combines 者 (person) and 見 (see), suggesting a person seeing or being seen. The exact historical development is uncertain, but the component combination is consistent with the meaning.
A person (者) using their eyes (見) to see: 覩 means to see or look.
For ト, imagine a person seeing a toe: toe -> ト, and the person (者) sees (見) it clearly.
