Cleanup or Clean Up – Quick Answer
✅ Cleanup → Noun or adjective, refers to the act of cleaning or something that facilitates cleaning.
Example: “The office needs a thorough cleanup before the meeting.”
✅ Clean up → Verb (phrasal), refers to the action of cleaning.
Example: “Please clean up your desk before leaving.”
❌ Incorrect: “Please do a clean up your desk.”
Tip: If it answers “what is being done,” use cleanup. If it answers “what to do,” use clean up.
The Origin of “Cleanup / Clean Up”
The verb clean up comes from the Middle English verb clenen, meaning “to make clean,” combined with up, indicating completion. Over time, English allowed verbs to form nouns or adjectives by combining them into a single word. Hence, cleanup emerged as a noun/adjective to refer to the result or process of cleaning.
This transformation is common in English: verbs can evolve into nouns by joining with prepositions (e.g., “makeup” from “make up,” “setup” from “set up”). Understanding this history helps explain why both forms exist and why context is key.
