What is the meaning of acutual not actual as different from actual?

"Acutual" is not a real word in the English language. It's likely a misspelling of "actual".

Actual means something that is real, true, or existing in fact, as opposed to something that is imagined, potential, or hypothetical.

Examples:

* "The actual cost of the project was higher than we expected."

* "This is the actual document, not a copy."

If you are seeing "acutual" written somewhere, it's likely a typographical error.
