Perguntas frequentes (8)
Yes, but only if you keep the 'not' with the verb. 'You should not go under any circumstances.' If you start with 'Under no circumstances,' you must invert.
Mostly, yes. It is very formal. However, you might hear it in a very serious speech or a heated argument where someone wants to sound authoritative.
It's a rhetorical device called 'Negative Inversion.' It draws the listener's attention to the negative condition immediately.
Actually, 'should' or 'may' are more common. 'Under no circumstances must you...' is grammatically possible but sounds slightly redundant because 'must' is already so strong.
The inversion still happens with the first auxiliary. 'Under no circumstances will John and Mary be invited.'
Usually, no. In negative inversion, we don't put a comma between the adverbial phrase and the auxiliary verb.
Yes! 'Under no condition' and 'On no account' follow the exact same inversion rules.
Yes, frequently. It is a high-level structure that examiners look for to award C1 or C2 marks in the writing and speaking sections.
