What are some alternatives to "is then"?

Is it correct to say "then is" instead of "is then"?
While "then is" might be grammatically valid in some contexts, it's less common and can sound awkward. "Is then" is generally preferred when indicating a logical sequence, while "then it is" can be used when you want to emphasize the 'then'.
What's the difference between "is then" and "is subsequently"?
"Is then" and "is subsequently" both indicate a sequence, but "is subsequently" emphasizes that a significant amount of time or other events might occur between the two actions. "Is then" implies a more direct or immediate consequence.
