Examples
SIMPLE

CONTEXTUAL

COMPLEX

“The situation in the city is far more dangerous than the reports suggest, believe you me.”

Origin

The idiom derives from an archaic English sentence structure characterized by the inversion of the subject and the verb for emphasis. It shares this grammatical foundation with the expression *I kid you not*, preserving a fossilised syntax that has otherwise largely exited standard modern usage.
