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.

FAQs
How to use "therefore I think" in a sentence?
You can use "therefore I think" as a transition after presenting evidence. For example: "The data is inconclusive; therefore I think we need further testing." You can also use alternatives like "<a href="/s/consequently+I+believe" target="_blank" rel="alternative">consequently I believe" or "<a href="/s/thus+I+conclude" target="_blank" rel="alternative">thus I conclude" depending on the context.
What can I say instead of "therefore I think"?
Common alternatives include "<a href="/s/consequently+I+think" target="_blank" rel="alternative">consequently I think", "<a href="/s/as+a+result+I+think" target="_blank" rel="alternative">as a result I think", or the more formal "<a href="/s/hence+I+believe" target="_blank" rel="alternative">hence I believe".
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.
Is "therefore I think" formal enough for academic writing?
