What does nonpublic mean?
Nonpublic means that something is not open or available to the general public. It is especially common in legal, governmental, business, and institutional settings, where it describes information, proceedings, records, or discussions that are private, confidential, or restricted to authorized participants. The word is more formal than a simple reference to something being “secret” and often suggests that access is limited by policy, law, or procedure. For example, a court may refer to nonpublic filings, while a company may warn employees about the nonpublic details of a planned transaction. Although “nonpublic” can describe anything not intended for public access, it is most useful when the restriction is institutional and clear. The prefix non- reverses the ordinary sense of “public,” making the adjective a precise way to distinguish private or confidential material from information that is officially open.

Where does nonpublic come from?
The word is formed from the combining form non-, meaning “not,” and public, which comes from Latin publicus, meaning “of the people” or “belonging to the state.” The compound has been used in English particularly in legal and institutional language to indicate that something is not open to public access. Its related forms—public, publish, publication, and republic—also reflect the Latin root publicus.
