Ludwig's WRAP-UP
In summary, "thus since" is a grammatically correct phrase used to establish a causal relationship between two connected ideas. As Ludwig AI confirms, it functions as a causal connector, explaining or justifying a conclusion based on a premise. While not the most frequent phrase, it appears across various domains, including science, news, and encyclopedias. It's essential to consider potential redundancy when using "thus since", as a single causal connector like "because" may suffice. When aiming for clarity and emphasizing both the cause and the effect, this phrase is an acceptable choice. The phrase tends toward a more formal register, making it most fitting in neutral to professional contexts. It's a good option when a more formal tone is needed in order to sound more authoritative.
