Clean out vs. Cleanout – Which is Correct?
“Clean out” and “cleanout” are both correct, but they have different grammatical roles. “Clean out” is a phrasal verb meaning to remove contents or empty a place. “Cleanout” is a noun for the act, event, or result of cleaning out. Use spaced form for actions and closed form for nouns.
Clean out or cleanout – Which is Correct?
Both clean out and cleanout are valid American English forms, but they are used differently. Clean out is generally a two-word phrasal verb. It describes an action, such as removing everything from a closet, garage, refrigerator, or account.
Cleanout is a one-word noun. It refers to the cleaning-out process, an organized event, or the result of removing unwanted items. The noun is less common than the verb phrase, and many writers may prefer alternatives such as cleanup, clear-out, or emptying depending on the context.
The Best Trick to Remember the Difference
Use the action test: if someone is doing something, write clean out as two words. If you are naming the activity, event, or result, write cleanout as one word.
For example, “We need to clean out the basement” describes an action. “The basement cleanout took all weekend” names the activity. You can also substitute empty for clean out; if the substitution works, the two-word verb is probably correct.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| clean out | Phrasal verb | To remove contents or unwanted items | They will clean out the storage unit. |
| cleanout | Noun | The act, event, or result of cleaning out | The office cleanout begins Friday. |
How to Use Clean out
Clean out is a phrasal verb that means to remove everything unwanted from a place, container, or space. It can also mean to empty something completely. The verb is common in casual and neutral everyday English, especially when discussing household chores, moving, storage, gardening, and organization.
The verb can be transitive, meaning it takes a direct object: clean out the garage. With pronouns, the object usually comes between the verb and the particle: clean it out, not normally clean out it.
Example 1: We need to clean out the attic before the renovation begins.
Example 2: She cleaned out her desk and donated the unused supplies.
Example 3: The mechanic told us to clean out the fuel tank before replacing the filter.
Etymology of the word clean out
Clean comes from Old English clǣne, meaning free from dirt or impurities. Out comes from Old English ūt, meaning outside or away from the inside. Together, the words developed into the phrasal verb clean out, emphasizing the removal of contents from an enclosed space.
How to Use Cleanout
Cleanout is a noun describing the process or occasion of cleaning out a place. It may refer to a household project, a business operation, a storage-unit sale, or the complete removal of contents. It is usually less frequent than clean out and can sound informal or specialized depending on the setting.
The noun often appears after an article or possessive determiner, such as a cleanout, the cleanout, or our cleanout. It can also modify another noun, as in cleanout sale or cleanout project.
Example 1: The spring cleanout gave us several boxes of clothes to donate.
Example 2: The store is holding a warehouse cleanout to make room for new inventory.
Example 3: After the tenant moved away, the landlord arranged a complete apartment cleanout.
Etymology of the word cleanout
Cleanout developed by combining the verb clean out into a noun. English commonly forms nouns from phrasal verbs by joining the words, as seen in terms such as breakout, checkout, and runoff. The spelling reflects the noun’s function rather than a separate root word.
