Expert writing Tips
Best practice
Avoid using the phrase "at then" in formal writing. Opt for grammatically correct alternatives like "at that time" or "back then" to maintain clarity and credibility.
Common error
A common error is to conflate "at" with "then" when trying to pinpoint a specific moment in time. Remember that "then" already implies a time reference, so using "at" before it creates redundancy and grammatical incorrectness. Instead, consider "at that time" or use "then" on its own within the sentence.
