How to use "under no circumstances"

What Does "under no circumstances" Mean?

• It expresses a strong degree of negation, indicating that something is absolutely not allowed or will not happen.
• It typically modifies the verb or the entire clause, emphasizing the prohibition or impossibility of an action or event.
• Register: formal

How to Use It

• The typical and most natural sentence position is initial. When placed at the beginning of a sentence, it requires inversion of the subject and auxiliary verb.
• It modifies the entire clause, adding a strong sense of prohibition or impossibility. It changes the meaning of a sentence by making it a firm and absolute denial.
• Grammatical flexibility: It can be fronted for emphasis, but this requires subject-auxiliary inversion. It is inherently negative and should not be used with additional negation. It is not typically used in questions.
• Using it in mid or final position sounds unnatural. Also, failing to invert the subject and verb after "under no circumstances" is grammatically incorrect.
