Expert writing Tips
Best practice
In formal academic papers or legal documents, consider using the uncontracted "that have not" to maintain a professional tone.
Common error
Writers often mistakenly use "that haven't" with singular collective nouns like 'group' or 'team' (e.g., 'the team that haven't'). While common in British English, American English typically requires 'the team that hasn't'. Always check your regional style guide for collective noun agreement.
