Ludwig's WRAP-UP
In summary, "because presumably" serves as a useful connector to introduce reasons based on assumptions or likelihoods. As Ludwig AI confirms, the phrase is grammatically sound and finds common usage across diverse contexts, including news, science, and formal writing. Remember to use it when you want to provide an explanation that's logical but not definitively proven. When formality matters, consider alternatives like "since it is likely" or "given that it's reasonable to assume". While versatile, avoid using it when you possess concrete evidence to maintain precision in your writing.
