Cleanup vs. Clean Up – Which is Correct?

The distinction between cleanup (one word) and clean up (two words) lies in their grammatical function. Cleanup is a noun or an adjective, referring to the act of cleaning or something related to it. Clean up, conversely, is a phrasal verb meaning to make something tidy, to resolve a situation, or to profit significantly.

Just as we differentiate ‘cleanup’ from ‘clean up,’ it’s important to grasp the nuances of other similar terms, such as Clean vs. Cleanse.

Cleanup or Clean Up – Which is Correct?

Both “cleanup” and “clean up” are grammatically correct in American English, but they serve different purposes. The key difference lies in their part of speech. “Cleanup” (one word) functions as a noun or an adjective, while “clean up” (two words) functions as a phrasal verb.

When you refer to the event or process of tidying, or describe something associated with that event, you use the single word “cleanup.” For example, a “cleanup operation” or “after the cleanup.” When you’re describing the action of making something tidy, you use the two-word phrasal verb “clean up.” For instance, “Please clean up your room.”

The Best Trick to Remember the Difference

A powerful trick to remember the difference is the “Part of Speech Swap Test.”

• If you can replace the word(s) with another noun (like “tidying,” “restoration,” or “mess”) or another adjective (like “restorative,” “organizational”), then you likely need the single word “cleanup.”
• If you can replace the word(s) with another verb phrase (like “tidy,” “organize,” “resolve,” or “profit”), then you likely need the two-word phrasal verb “clean up.”

Think: “a big cleanup” (noun) vs. “to clean up the mess” (verb).

Word	Part of Speech	Meaning	Example
cleanup	Noun or Adjective	Noun: The act or process of cleaning something. Adjective: Relating to an act of cleaning.	The town organized a beach cleanup. (Noun) We need a cleanup crew. (Adjective)
clean up	Phrasal Verb	To make something tidy or clean; to resolve a problem; to make a large profit; to finish an activity.	Please clean up your room. (Verb) The company needs to clean up its act. (Verb)

How to Use Cleanup

“Cleanup” is used as a single word when it functions as a noun or an adjective. As a noun, it refers to the act or process of cleaning, tidying, or restoring. It can also refer to the result of such an action. As an adjective, it modifies another noun, describing its purpose or association with cleaning. Its tone is generally neutral and can be used in both formal and informal contexts.

Example 1: After the festival, a massive cleanup effort was required. (Noun – referring to the event/process)

Example 2: The environmental group organized a river cleanup day for volunteers. (Adjective – describing the type of day)

Example 3: The financial scandal necessitated a complete regulatory cleanup. (Noun – referring to the act of rectifying a situation)

What are the different forms of Cleanup?

As a noun, “cleanup” can be singular or plural:

• Singular: cleanup (e.g., “a major cleanup”)
• Plural: cleanups (e.g., “several cleanups are planned”)

As an adjective, “cleanup” does not typically take comparative or superlative forms (e.g., “more cleanup”). It functions as a descriptive adjective.

Etymology of the word Cleanup

The word “cleanup” as a single-word noun or adjective emerged later than the phrasal verb “clean up.” It developed through a process called nominalization, where a verb phrase becomes a noun, or compounding, where two words are joined. Its usage as a noun became common in the early 20th century, particularly in American English, to denote the act or instance of cleaning or restoring order, often in a large-scale or organized manner.

How to Use Clean Up

“Clean up” is a versatile phrasal verb, meaning a verb combined with a preposition or adverb that creates a new meaning. It generally means to make something tidy or neat, but it can also have several idiomatic meanings:

• To put things in order: “Please clean up your desk.”
• To resolve a problem or difficult situation: “The new CEO was hired to clean up the company’s finances.”
• To make a large profit or gain: “He really cleaned up at the casino last night.”
• To finish or complete something, especially eating or drinking: “The kids cleaned up all the cookies.”

This phrasal verb can be separable (the object can come between “clean” and “up”) or inseparable, depending on the context.

Example 1: We need to clean up the kitchen before guests arrive. (To make tidy)

Example 2: The government promised to clean up corruption within the department. (To resolve a problem)

Example 3: After years of hard work, the entrepreneur finally cleaned up with his new invention. (To make a large profit)

What are the different forms of Clean Up?

As a phrasal verb, “clean up” follows standard verb conjugations. Here are some common forms:

• Base Form: clean up (e.g., “They clean up every Saturday.”)
• Past Simple: cleaned up (e.g., “She cleaned up the spill.”)
• Past Participle: cleaned up (e.g., “The room has been cleaned up.”)
• Present Participle/Gerund: cleaning up (e.g., “He is cleaning up the yard.” / “Cleaning up is important.”)
• Third Person Singular Present: cleans up (e.g., “He cleans up his workspace daily.”)

Etymology of the word Clean Up

The phrasal verb “clean up” combines the Old English word “clæne” (meaning pure, clear, unblemished) with the adverb “up.” The word “clean” itself has Germanic roots. The addition of “up” emphasizes completion or thoroughness of the action. This combination to form a phrasal verb with the meaning of tidying or completing a task has been in use for centuries, predating the single-word noun/adjective form.

Related Concepts

Understanding a few broader grammar concepts can help solidify your grasp of the distinction between “cleanup” and “clean up.”

• Phrasal Verbs: These are combinations of a verb and an adverb or preposition (or both) that create a new meaning distinct from the individual words. “Clean up” is a classic example, where “clean” (the verb) combines with “up” (the adverb) to mean “to tidy.”
• Compound Nouns: These are nouns made up of two or more words that function as a single unit. “Cleanup” (as a noun) is a compound noun, often formed by joining a verb and a preposition/adverb. Other examples include “breakdown,” “takeaway,” and “workout.”
• Parts of Speech: Recognizing whether a word is a noun, verb, adjective, or adverb is fundamental. This distinction is the core of understanding when to use “cleanup” (noun/adjective) versus “clean up” (verb).

• “The author described the aftermath of the storm, focusing on the community’s swift cleanup efforts.” (Noun)
