Expert writing Tips
Best practice
Rephrasing can avoid awkwardness and improve readability. For example, instead of saying "it fails then when", try "it fails specifically when" or "failure occurs at the point when".
Common error
Avoid combining multiple conditional markers like "then when" as it can make the sentence structure convoluted. Instead, focus on direct and clear phrasing such as "it fails when" to prevent misunderstanding.
