The inconvenience caused to you hereof is highly regretted Is the sentence grammatically correct?

The sentence "The inconvenience caused to you hereof is highly regretted" is grammatically correct, but it is quite formal and outdated.

Here's why:

* "Hereof" is archaic: While technically correct, "hereof" is rarely used in modern English. It sounds stiff and formal.

* "Highly regretted" is formal: This phrase is more common in formal written communication.

Here are some better ways to express the same sentiment:

* "We sincerely apologize for any inconvenience this may cause." (More direct and modern)

* "We regret any inconvenience this may cause." (More concise and still polite)

* "We apologize for any trouble this may cause." (More casual)

The best choice will depend on the context and tone of your communication.
