Here’s a long adjective with a short definition: incontrovertible means “not open to question”, “indisputable”, “impossible to deny”, or, phrased another way, “necessarily or demonstrably true”. I prefer any of those definitions over “not controvertible”. Why does Dictionary.com even bother including that? :roll:
Anyway, as you can probably guess, this word is related to controversy, which comes from Latin contra-, meaning “against”, and versus, meaning “to turn”. And apparently there’s even a verb controvert, meaning “to argue against”. I’ve never seen it before, but a quick search reveals that it does show up in recent news articles.
I thought I’d come up with a clever little sentence that uses all these similar words together, but others already have, as in “controvert the incontrovertible”. I liked this phrase from somebody’s academic retort (about I don’t know what): “I say that the evidence was incontrovertible because you did not try to controvert it.”
