FAQs
How can I use "and is therefore" in a sentence?
Use "and is therefore" to connect two clauses where the second clause is a direct result of the first. For example, "The data was flawed, and is therefore unreliable."
What are some alternatives to "and is therefore"?
You can use alternatives like "and thus", "and consequently", or "and as a result" depending on the specific nuance you want to convey.
Is "and is therefore" formal or informal?
"And is therefore" is suitable for both formal and neutral contexts. While not overly informal, alternatives like "so" or "therefore" alone might be preferred in very casual writing.
