Expert writing Tips

Best practice

Use this phrase to connect a clear premise to your subjective conclusion, ensuring the logical link is evident to the reader.

Common error

Avoid starting sentences with 'So therefore' or 'And therefore'. Since 'so', 'and', and 'therefore' all serve to connect ideas, using two together is often redundant in professional writing. Choose the one that best fits the desired level of formality.

Should I use a comma after "therefore" in "therefore I think"?

Yes, in formal writing, it is standard practice to place a comma after 'therefore' when it begins a sentence or an independent clause, such as "Therefore, I think it is the right choice." However, in more fluid journalistic styles, the comma is sometimes omitted for pace.
