1. Popular, simple, commonplace.
  2. Suitable to be communicated to the general public.

Not to be confused with esoteric, which means intended for or likely to be understood by specialists.

The best way to avoid confusion between these antonyms is to focus on the prefixes.

“Ex-” indicates “out”, so the word exoteric can be thought of as an outward dissemination of information.

“Es-” indicates a separation, so the word esoteric can be linked to the development of information by experts.

What is esoteric becomes exoteric by the use of clear explanations.
