Expert writing Tips
Best practice
Avoid using "whether since" as it combines two conjunctions in a grammatically incorrect way. Choose either "whether" to express a choice between alternatives or "since" to indicate a reason or time.
Common error
Do not conflate conditional and causal conjunctions. "Whether" indicates a choice, while "since" denotes cause or time. Combining them leads to ungrammatical sentences.
