The mouth can turn into a knife.
The mouth can turn into a knife.
Meaning in plain English
A mouth turning into a knife gives speech an image of injury. The saying asks a speaker to recognise how words may hurt.
Example
Someone raises an important concern without adding a degrading personal remark.
Deeper explanation and when to use it
The metaphor is not a physical mechanism or a judgment that all forceful language is wrong. A responsible application distinguishes humiliation or false accusation from necessary objection and reporting. Clear speech can protect people, and a difficult truth is not automatically cruelty.
When to use it
Use it to discuss speech’s consequences alongside necessary clarity.
Keep in mind
No universal harm from speaking or duty to suppress justified criticism is established.
