Ludwig's WRAP-UP
In summary, "a rationale for why" is a commonly used phrase that introduces a clear and logical explanation. As Ludwig AI confirms, it's grammatically correct and well-suited for formal contexts such as academic papers, news articles, and scientific reports. It serves the purpose of informing or persuading by providing well-supported reasoning. While alternatives like "the reason why" exist, "a rationale for why" specifically implies a more developed and articulated justification, therefore when writing, one should consider the redundancy in the statement, avoiding state the obvious.
