Ludwig's WRAP-UP

In summary, while "As then" is occasionally used, it is generally considered grammatically incorrect in formal English. Ludwig AI points out that clearer alternatives such as "at that time" or "back then" are preferred for better clarity and precision. Its main purpose is to establish a temporal relationship, but its questioned correctness suggests using it carefully, mainly in informal contexts. Authoritative sources such as The Guardian and The New York Times provide some examples, but these should be viewed with the understanding that better alternatives often exist.
