Common Errors to Avoid
1. Lack of Parallelism:
When using “not only…but also,” both parts of the sentence should have the same grammatical structure. For example:
- Incorrect: He not only enjoys swimming but also to run.
- Correct: He not only enjoys swimming but also running.
2. Double Negatives:
Avoid using a negative phrase after “not only.” This can make the sentence confusing or grammatically incorrect. [not only but also]
- Incorrect: Not only did she not attend the meeting, but she also didn’t inform us.
- Better: Not only did she skip the meeting, but she also failed to inform us.
3. Overusing Inversion
While inversion can add emphasis, using it too often in casual conversations may sound unnatural. Reserve it for formal or impactful statements.
