Expert writing Tips
Best practice
When using "rationales", ensure the contrasting element introduced by "but" is clearly and logically connected to the preceding rationales. The relationship should be evident to maintain clarity.
Common error
Avoid using "rationales but" when the "but" doesn't introduce a true contrast. Ensure that the clause following "but" genuinely offers an opposing viewpoint or limitation to the preceding rationales, not just an additional piece of information.

Ludwig's WRAP-UP
In summary, the phrase "rationales but" is intended to bridge justifications with a contrasting element. However, Ludwig AI identifies it as grammatically incorrect and suggests using stronger, more explicit conjunctions like "however" or "nevertheless" for improved clarity and formality. While appearing in sources like The New York Times and scientific journals, its rare usage indicates it should be approached with caution. Instead, opt for alternatives such as ""rationales however"" to ensure grammatical correctness and precision in writing.
