1. Ignore the error: Most grammar checkers allow users to skip or ignore suggestions they do not agree with or find irrelevant. If you are confident that the flagged “error” is not an issue, you can bypass the suggestion and move on to the next one.
2. Review the context: Take a moment to thoroughly review the context surrounding the flagged error. Sometimes, the initial correct usage might still create confusion or ambiguity within the specific context, and reconsidering the phrasing could improve overall clarity.
