Ludwig's WRAP-UP

In summary, "I then realised" is a common and grammatically sound phrase used to indicate a moment of understanding that follows a previous action or thought.

While versatile, it's best used to describe reactive awareness rather than proactive planning. Alternatives like "I then understood" or "I subsequently realized" can provide subtle variations in meaning, and it's important to maintain spelling consistency (realised vs. realized) based on the intended audience.
