Origin and Etymology
The intensifying use of "clean" meaning "completely" dates back to older English and Scots usage and was carried into American English through early settlement. While many such constructions faded from general use, this pattern remained productive in Southern and Appalachian speech, where "clean" continues to function as an adverbial intensifier in everyday language. The phrase reflects regional preservation rather than Southern origin.
Usage Notes
"Clean through" is still used in Southern and Appalachian speech to stress that something was done fully, without skipping steps or stopping partway. Outside these regions, the phrase is uncommon and often sounds old-fashioned or dialectal, with speakers favoring alternatives like "all the way through."
