exoteric

intended for or understandable by the general public

Exo means outside. Exoteric knowledge faces outward, toward ordinary readers instead of an inner circle.

The professor wrote an exoteric version of the theory for readers outside the field.

Exoteric is the outside-facing partner of esoteric. It does not mean shallow. It means public, open, or meant for a wider audience.

The pair is useful: esoteric points inward to the initiated few; exoteric points outward to the many.
