Ludwig's WRAP-UP
In summary, "but hitherto" is a grammatically sound adverbial phrase used to signal a contrast with a previous state, as validated by Ludwig AI. While versatile, it's most appropriate for formal and scientific writing. For less formal contexts, simpler alternatives like "but until now" are preferable. Its widespread use in reputable publications such as The Economist and Nature solidifies its standing as a valid, although somewhat formal, element of English vocabulary. When looking for a replacement, be mindful that there are many phrases that do this task of time-shifting, but you have to choose the one that fits well within your semantic context.
