Expert writing Tips
Best practice
Use "thus why not" to smoothly transition from a premise or established fact to a suggestion or rhetorical question that logically follows. This can create a compelling invitation to consider an action or idea.
Common error
Avoid using "thus why not" as a mere substitute for a simple "why not". "Thus" implies a direct logical consequence; ensure the suggestion genuinely follows from a previously stated point. Otherwise, use "why not" directly.

Ludwig's WRAP-UP
In summary, the phrase "thus why not" functions as a causal connector that introduces a suggestion logically linked to preceding information. While Ludwig confirms its grammatical correctness, it is a relatively rare phrase that is predominantly found in scientific and news media contexts. The most effective use of "thus why not" involves ensuring a clear and direct causal relationship between the initial statement and the subsequent suggestion. It's important to avoid using this phrase as a simple substitute for 'why not' if that relationship isn't present. Furthermore, consider alternatives like "therefore why shouldn't we" or "hence why not consider" to vary your writing style.

FAQs
How can I effectively use "thus why not" in a sentence?
Use "thus why not" to introduce a suggestion or rhetorical question that directly and logically follows from a previous statement or established fact. It emphasizes the consequential nature of the suggestion. For example, "We've identified the problem; thus why not implement the solution immediately?"
What are some stylistic alternatives to "thus why not"?
Depending on the context, you might consider alternatives like "therefore why shouldn't we", "hence why not consider", or "given this, why not try". Each subtly shifts the emphasis but maintains the consequential link. See also "accordingly why hesitate".
Is "thus why not" always appropriate, or are there situations to avoid?
"Thus why not" works best when the suggestion or question is a clear and direct consequence of what precedes it. Avoid using it if the connection is weak or unclear, as it can sound forced or illogical. In those cases, a simpler "why not" might be more suitable.
What's the difference between "thus why not" and a simple "why not"?
The addition of "thus" indicates a logical connection between the prior statement and the suggestion that follows. A simple "why not" is a more general inquiry or suggestion, without necessarily implying a direct causal relationship. Thus, "thus why not" adds emphasis.
