Do you know the idiom ‘clean as a whistle’?
When we say something is as ‘clean as a whistle’ we mean that it is thoroughly clean or pure.
Origin – the story:
There are several ideas about the origin of this idiom. For example, one is that the word ‘clean’ was changed from clear, because ‘clear as a whistle’ was used to refer to the clear, pure sound of a sword swishing through the air, particularly when decapitating someone. There is an example of this used in the 19th century: ‘a first rate shot. (his) head taken off as clean as a whistle’.
Example: The application process involves security checks to make sure that everyone is clean as a whistle.
