Have you heard about that esoteric book club in town?

No, I haven't! What's so special about it?

That sounds interesting, but also a bit intimidating!

Root Explanation

Esoteric is formed from "eso-" (from Greek "esō", meaning within) and "terikos" (from Greek "terikos", meaning of or pertaining to). The word describes knowledge that is intended for or likely to be understood by only a small number of people, hence it is knowledge that is 'within' a select group.

Memory Tip

Think of knowledge that is 'within' a small group — that's why esoteric refers to specialized or secret knowledge.
