Etymology

Origin of demonstrable

First recorded in 1350–1400; Middle English, from Old French, from Late Latin dēmonstrābilis, equivalent to Latin dēmonstrā(re) ( see demonstrate) + -bilis -ble

Explanation

If something is demonstrable, it can be shown or proven to be true, making it clear to anyone who looks at the evidence. The adjective demonstrable comes from the verb demonstrate, which means "to establish the validity of something" or "to provide evidence for." If a lawyer in court states that it's a demonstrable fact that a defendant behaved with negligence, it means that they can prove it with hard facts.
