Expert writing Tips

Best practice

Avoid using "confirm of". Use "confirm" followed by the item being confirmed directly (e.g., "confirm the details") or use a more appropriate preposition like "confirm in" or "confirm with" if needed.

Common error

The preposition "of" is often incorrectly paired with "confirm". Instead, ensure you are using the correct preposition (such as "in" or "with") or, most commonly, no preposition at all. For instance, say "confirm the reservation" not "confirm of the reservation".

Ludwig's WRAP-UP

In summary, the phrase "confirm of" is grammatically incorrect in standard English. As Ludwig AI highlights, the correct usage is typically "confirm" followed directly by the object being confirmed. While it might occasionally surface in informal contexts or due to errors, it's best to avoid this construction in formal, professional, or academic writing. Instead, opt for alternatives like "verify", "validate", or simply use "confirm" correctly to ensure clarity and accuracy in your writing.

FAQs

What is the correct way to use "confirm" in a sentence?

The word "confirm" is typically followed directly by the object you are confirming. For example, "Please confirm your email address" or "The data confirm the hypothesis."

What can I say instead of the incorrect phrase "confirm of"?

Instead of "confirm of", you should use "confirm" followed by the object you are verifying. Alternatives include phrases like "verify", "validate", or "substantiate", depending on the context.

Is "confirm of" grammatically correct?

No, "confirm of" is not grammatically correct in standard English. The correct usage is usually "confirm" followed directly by the object being confirmed.

How do I ensure I'm using "confirm" correctly in my writing?

Double-check that you are not inserting an unnecessary preposition after "confirm". For instance, it should be "confirm the booking" rather than "confirm of the booking". If you're unsure, try replacing "confirm" with "verify" to see if it makes sense.
