Ludwig's WRAP-UP

The phrase "in addition since" is flagged by Ludwig AI as grammatically incorrect, despite its relatively frequent appearance across diverse sources like News & Media, Encyclopedias, and Science. This phrase tries to combine the functions of adding information ("in addition") and indicating causality ("since") but does so in a way that violates standard English grammar. To express both ideas correctly, it's best to separate them into distinct phrases or clauses, using constructions such as "additionally, because" or "in addition, considering that". Although usage exists, prioritizing clarity and grammatical accuracy is advisable, especially in formal writing.
