Expert writing Tips
Best practice
When using "about half of all", ensure that the context provides a clear total or reference group to which the 'half' applies. For example, "About half of all students passed the exam" is clear, while "About half of all" alone is ambiguous.
Common error
Avoid using "about half of all" without specifying what the 'all' refers to. Saying "About half of all is sufficient" lacks clarity; clarify with something like "About half of all respondents found the survey sufficient."
