Usage

What does esoteric mean? Esoteric most commonly means obscure and only understood or intended to be understood by a small number of people with special (and perhaps secret) knowledge. It’s often used to describe knowledge that’s only intended to be revealed to people who have been initiated into a certain group. The word is often associated with mysticism and the occult. Such knowledge can be collectively referred to as esoterica, which can also refer collectively to books and other works that contain such topics. Example: To the uninitiated, this kind of esoteric knowledge is impenetrably arcane.

Etymology

Origin of esoteric

First recorded in 1645–55; from Greek esōterikós “inner,” equivalent to esṓter(os) “inner” + -ikos -ic

Explanation

Pssst... do you know the secret handshake? If you haven't been brought into the inner circle of those with special knowledge, esoteric things will remain a mystery to you. In the olden days, achieving esoteric knowledge meant getting initiated into the mystical arts, learning secrets unknown to regular folks. Now when a subject is called esoteric it's usually something not so mystical but still hard to penetrate: financial accounting might seem esoteric for people who get easily stumped filling out their tax forms. Americans might find the sport of cricket to be esoteric, but the rules of baseball can be just as impenetrable to outsiders. The infield fly rule? Totally esoteric.
