Grammar usage guide and real-world examplesUSAGE SUMMARY
"subsequently then" is not correct and should not be used in written English.
The word "subsequently" means "afterward" or "later," while "then" means "at that time" or "next." Since both words have similar meanings, using them together would be redundant and awkward. It would be better to choose one or the other, depending on the context. Example: Incorrect: He finished his dinner and subsequently then went for a walk in the park. Correct: He finished his dinner and subsequently went for a walk in the park. or Correct: He finished his dinner and then went for a walk in the park.

Expert writing Tips
Best practice
Avoid using "subsequently then" in your writing. Choose either "subsequently" or "then" to maintain clarity and grammatical correctness.
Common error
Using both "subsequently" and "then" together creates a redundancy. "Subsequently" already implies "afterward" or "later", so adding "then" is unnecessary and weakens your writing.

Ludwig's WRAP-UP
In summary, the phrase "subsequently then" is considered grammatically incorrect due to its redundant nature. As Ludwig AI explains, both "subsequently" and "then" serve a similar purpose, indicating a sequence in time. Therefore, using them together is unnecessary and detracts from clarity. While examples exist across various sources like science, news, and wiki, opting for either "subsequently" or "then", or alternative phrases such as "afterward", is recommended for clearer and more effective communication. Avoid using the phrase in formal writing.

FAQs
Is "subsequently then" grammatically correct?
No, "subsequently then" is grammatically incorrect because it's redundant. The word "subsequently" already includes the meaning of "then", so using both together is unnecessary. Use either "subsequently" or "then" separately.
What can I use instead of "subsequently then"?
Instead of "subsequently then", you can use single words such as "subsequently", "then", or "afterward". You could also use phrases like "following that" or "after that".
What is the difference between "subsequently" and "subsequently then"?
"Subsequently" means "afterward" or "later". "Subsequently then" is redundant because "then" is already implied in the meaning of "subsequently". Therefore, using just "subsequently" is correct and more concise.
How do I avoid redundancy when writing about sequential events?
To avoid redundancy, choose words carefully and be aware of their implied meanings. For example, instead of saying "repeat again", just say "repeat", or, as in this case, avoid using "subsequently then" and choose either "subsequently" or "then".
