under no circumstances =not for any reason, e. g. Under no circumstances should you go out alone.
این یک ساختار گرامری هست که به خاطر inversion ای ک درش اتفاق میفته معروفه . یعنی میگیم: Under no circumstances, will we take these measures به جای اینکه بگیم: Under no circumstances, we will take these measures
for anything I wouldn’t go back there for anything
