Expert writing Tips
Best practice
Use "but then subsequently" to clearly indicate a sequence of events, particularly when the second event is unexpected or contrasts with the first. This can improve clarity in complex narratives or instructions.
Common error
Be mindful that "but then" already implies a sequence. Using "subsequently" immediately after can be redundant. Consider if "but then" alone suffices to convey the intended meaning or if "subsequently" adds significant emphasis.

Ludwig AI confirms its validity and common usage. While predominantly found in news and scientific contexts, its formality level ranges from neutral to formal.
