How it's used
Reserved for formal or high stakes contexts, this term is rarely used in casual daily chatter. It often appears in professional settings, news reports, or when discussing sensitive information that requires strict protection. Unlike general terms for secret, it carries a weight of authority and official security.
Examples
This document is very confidential and cannot be shown to others.

Common mistake
