How it's used

This idiom carries a formal and cautionary tone, often used to warn someone about the permanence of their speech. While it originates from classical literature, it remains a standard way in modern Cantonese to emphasize that spoken words are like horses pulling a chariot that cannot be stopped once they start running. It is most effective when used in serious advice or when someone is about to regret a hasty comment.

Examples

Once you say it, you can't take it back, think carefully before you speak.
Do you know what it means to be unable to take back words? Once you say the wrong thing, there's no turning back.

Common phrases

Be careful with your words, you cannot take them back.

Common mistake

Learners often mistake this for a common daily expression, but it is actually a formal idiom that sounds quite heavy in casual conversation. Using it in a lighthearted or trivial situation can make the speaker sound overly dramatic or pedantic.
