Noun of your business意思
The phrase "noun of your business" is not a standard English expression and does not have a clear, fixed meaning in the context of business or any other context. It seems to be a non-standard construction that may have been intended to convey a meaning similar to "nature of your business," which is a common expression meaning the type or character of the business one is involved in.
If you are looking for the "noun of your business," it could be interpreted as the name or title of your business, but this is not a standard usage. In any case, if you provide more context or clarify your question, I would be happy to offer a more precise answer.
