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.
Do you know that this is a confidential mission?

Common phrases

confidential document

Common mistake

Avoid using this to describe personal secrets between friends, as it sounds overly formal and bureaucratic. For private matters, use 秘密 instead.
