Demonstrably means “in a way that can be shown or proved” — so clearly that the evidence is there to point at. If a plan is demonstrably cheaper, you can set the two bills side by side. If someone is demonstrably wrong, it is not a matter of taste; you can show the mistake. Though actually, writers sometimes use it as a heavy “obviously,” even when they have not really produced the proof yet. A careful reader waits to see whether the evidence follows. It is a formal adverb, common in essays, news analysis, and academic talk, not in everyday chat. First used in English in the early 1600s.
