Ludwig's WRAP-UP
In summary, the phrase "previously then" attempts to link two past events sequentially, yet it frequently results in redundancy, making it non-standard in English writing. Ludwig AI marks this as a potentially confusing construction. While it appears across diverse sources like Science and News & Media, clearer options like "previously" or "then" alone, or alternatives such as "before that", "subsequently" and "formerly" are recommended for enhanced clarity. Avoid "previously then" in formal writing to steer clear of awkward phrasing and potential misinterpretations.

FAQs
How can I use "previously then" in a sentence correctly?
While "previously then" isn't considered standard English, you might use it to emphasize a sequence. However, it's often clearer to use either "previously" or "then" separately or rephrase. For example, instead of saying "We had an issue, and "previously then" another issue occurred" consider saying "We had an issue, and "subsequently" another issue occurred".
What can I say instead of "previously then"?
Alternatives include "previously", "then", "before that", or "subsequently". The best choice depends on the context and the specific nuance you want to convey.
Is it grammatically correct to use "previously then"?
While not strictly ungrammatical, "previously then" is often considered redundant and stylistically weak. It is generally better to choose one word or rephrase for improved clarity and flow.
What's the difference between using "previously" and "previously then"?
"Previously" indicates something that happened before the current time or event. "Previously then" attempts to combine this with the sequential nature of "then", but this can create redundancy. In most cases, "previously" or "then" alone will suffice, or you might need to rephrase the sentence to emphasize the sequence more clearly.
