What is the origin of the phrase ‘clean as a whistle’?

The origin of the simile ‘clean as a whistle; is still a matter of debate, including both the first recorded use of the phrase and why a whistle.

One theory goes back to the famous Scottish poet Robbie Burns. In his book Author’s Earnest Cry published in 1786, Burns wrote a phrase very similar to ‘clean as a whistle’: “Her mutchkin stowp as toom’s a whissle” which meant “Her pint bucket is as empty as a whistle”. Here it is believed that Burns was familiar with the workings of a whistle and knew that it is only when a whistle is clear of any obstruction that it will work properly and produce a good, clear, pure sound.

Another theory dates back to the early 1800s where the simile was used to describe the whistling sound that’s made when a sword swishes through the air when it’s being used to cut someone’s head off, in the quotation: ‘A first rate shot.(his) head taken off as clean as a whistle.’ While perhaps an intriguing theory, this theory is less well documented, and may be more folklore than a substantiated origin.

However, in her book “Have A Nice Day — No Problem, A Dictionary of Cliches” Christine Ammer says the phrase “clear as a whistle” (rather than ‘clean as whistle’) was very common in the 1700s when it came to describe something as “unmistakable” or “unambiguous”. She then adds that the word may have drifted from ‘clear’ to ‘clean’. This theory is supported by documented linguistic shifts and is a credible explanation for the phrase’s evolution.
