- ❌ The clean up was successful. (wrong)
Simple rule:

The Origin of Cleanup or Clean Up
The phrase “clean up” comes from Old and Middle English, where “clean” functioned as an adjective and verb meaning “to make pure or tidy.” Over time, English developed phrasal verbs, combining verbs with particles like up, out, or off.
As English evolved, many phrasal verbs created compound nouns by joining words together. That’s how “clean up” (verb) became “cleanup” (noun).
This pattern appears in many English words:
- set up → setup
- break down → breakdown
- check out → checkout
The spelling difference exists because grammar determines form, not preference.
