Ludwig's WRAP-UP
The phrase "then then" is frequently found, but its grammatical status is questionable. As Ludwig points out, it is generally considered incorrect in formal writing. Analysis of its function reveals it aims to emphasize sequence or consequence, and it appears more often in informal contexts such as general discussions or Wiki articles, although it does surface in some news outlets too. When clarity and grammatical correctness are paramount, it's advisable to opt for alternatives like "and then" or "subsequently". While it might be used for emphasis, the risk of being perceived as repetitive or unpolished is high. Therefore, use "then then" sparingly, if at all, particularly in professional or academic settings.
