Best practice

Avoid using "first subsequently" as it's grammatically incorrect. Instead, use "at first, then" or "initially, followed by" for clarity and correctness.

Ludwig's WRAP-UP

In summary, the phrase "first subsequently" is grammatically incorrect and should be avoided.

Instead, use alternatives like "at first, then" or "initially followed by" to clearly and correctly express sequential events. The phrase appears rarely, predominantly in scientific and news contexts, underscoring the importance of choosing more appropriate wording.
