Introduction

Idioms are expressions whose meanings are not predictable from the usual meanings of its constituent elements. They are a crucial part of the English language, adding nuance and color to communication. Correct usage of idioms demonstrates a strong command of the language. The given sentence, "The police no stone unturned to trace the culprits," contains a common error in idiom usage.
