Ludwig's WRAP-UP
In summary, the phrase "and therefore because" is generally considered grammatically incorrect due to its redundant use of conjunctions. While it appears in various sources, as shown by Ludwig's examples, it's best to avoid this phrase in favor of clearer and more concise alternatives such as "therefore" or "because" alone. As Ludwig AI points out, the combination of both terms adds unnecessary complexity and reduces the clarity of your writing. Opting for alternatives enhances both the correctness and the impact of your sentences.
