Character 诫, to Warn

A serious warning or admonition. It names the act of telling someone to warn them, take heed, change course, or avoid a fault.

You almost never see it alone in normal writing; look for it inside formal compounds, where the surrounding words decide whether the warning feels parental, official, or literary.

is 诫 the same as 戒?

They are related, but not interchangeable.

Classical Chinese sources use 戒 for guarding, self-caution, and admonition; 诫 developed with a speech side to mark a warning given in words. Traditional writing uses 誡. As of 2026, no secure first manuscript or bronze-inscription date for 诫 itself is established.

when does 诫 sound harsh?

When it stands alone as your reply.

A bare 诫 can sound like a reprimand, so use a fuller phrase when you need warmth. In a title, formal notice, or deliberate warning, that sternness is usually the point.
