How it's used
Focuses on the futility of communication when the listener is unwilling to change their mind or incapable of understanding. It carries a strong sense of frustration or resignation, often implying that the speaker has already tried to explain themselves to no avail. Use this when you want to emphasize that further discussion is pointless.
Examples
He doesn't listen to anyone at all, so no matter how much you say, it's just a waste of breath.
Trying to reason with him is a complete waste of breath, let's just forget it.
Related words
Common phrases
simply a waste of breath
don't want to waste my breath
Common mistake
Do not confuse this with 嘥氣, which is a broader term for wasting effort or energy. While 嘥氣 can also refer to wasting breath, 嘥口水 specifically highlights the act of speaking or trying to persuade someone.
