The word controvertible means “capable of being disputed or opposed by reason”
First usage
Our word came into English in the early 1600s
Background / Comments
I find it interesting that the more common opposite word – incontrovertible – is the newer word. There are many words that are opposites, but one is far more common that another word; for example, “disgruntled” is better known than its opposite “gruntled”. Our word came from the English word controvert (to dispute or oppose by reasoning), which came from Anglo-French, which came from the Latin word controversus (disputable), which is made up of contro- (against) and versus, the past participle of vertere (to turn).
