In Southern and Appalachian speech, clean out means completely gone or entirely used up, referring to a total absence of something that was once available.
★ This use of clean out doesn’t need an object - if folks know what you’re talkin’ about, the meaning’s already clear. ★
Origin and Etymology
The use of "clean" as an adverbial intensifier meaning "completely" traces back to older English and Scots forms carried into American English through early settlement. In Southern and Appalachian speech, this intensifier pattern remained productive, allowing phrases like "clean out" to function independently to indicate total depletion. This reflects regional preservation rather than Southern origin.
Usage Notes
"Clean out" is commonly used in Southern and Appalachian speech to indicate that nothing remains of a particular item, supply, or resource, often without stating the object explicitly. In other regions, speakers more often use phrases like "sold out" or "all gone."
