Expert writing Tips

Best practice

When intending to convey a sequence of actions, it is better to use "and then" or "then" alone to ensure clarity and grammatical correctness.

Common error

Avoid using "in then" to link events sequentially. This construction is often grammatically incorrect and can confuse readers. Instead, opt for "and then" or simply "then".

Ludwig's WRAP-UP

The phrase "in then" is generally considered grammatically incorrect in standard English, as noted by Ludwig AI. While it appears frequently across various sources, including News & Media and Science, its usage often represents colloquial speech or specific scientific contexts where "in" refers to set membership, making it a potential source of confusion. To ensure clarity and grammatical correctness, it's recommended to use alternatives such as "and then" or simply "then" to indicate a sequence of actions. When aiming to show consequence, phrases like "as a result" or "therefore" are more appropriate.
