Esoteric means understood by, or intended for, only a small group of people who possess specialized knowledge or training. The word emphasizes that access depends on background study rather than public secrecy. A mathematical notation, an academic argument, or a trade method can be esoteric to newcomers while remaining standard practice for trained specialists.

The software manual avoided esoteric acronyms and described each feature with familiar examples.
