Expert writing Tips
Best practice
For clarity, consider rephrasing sentences using "and therefore when" to use separate clauses. This improves readability and avoids potential ambiguity. For example, instead of "The experiment failed, and therefore when we repeated it, we adjusted the parameters", try "The experiment failed. Therefore, when we repeated it, we adjusted the parameters."
Common error
Avoid stringing together too many conjunctions and adverbs in one sentence. Overuse of phrases like "and therefore when" can make your writing sound convoluted. Break down complex sentences into simpler ones for better clarity.
