copy on this
Grammar usage guide and real-world examplesUSAGE SUMMARY
The phrase "copy on this" is not grammatically correct or commonly used in written English.
It may be a shortened form of "copy written on this" or "copy of this," but it is unclear and could potentially be interpreted as a mistake or typo. If you are trying to indicate that something has been copied or written on a specific document or page, it would be more clear to say "see copy on this document" or "written on this page." Alternatively, you could simply use the word "copy" as a noun, such as "please provide a copy of this document" or "I have a copy of the report." Incorrect: The memo contained copy on this. Correct: The memo contained a copy of the report.
