Expert writing Tips
Best practice
Use "not only do I" to emphasize that you're adding an important point or action in addition to something else you've already mentioned. Make sure to follow it with "but" and the additional clause to complete the structure.
Common error
Avoid using "not only do I" without completing the structure with a "but" clause. The phrase sets up an expectation that you will add a related piece of information, so failing to do so makes the sentence incomplete and less impactful.
