Etymology
Origin of presumptive
From the Late Latin word praesūmptīvus, dating back to 1555–65. See presumption, -ive
Explanation
Having a good reason to believe that something is true means that it is presumptive — you could call a person you assume will be nominated for school president the "presumptive nominee." After an election, when the votes are still being counted but it's clear who the winner will be, reporters often talk about that person as the presumptive winner. And if a doctor were fairly certain you had strep throat, she might call it her presumptive diagnosis. The Latin root word is praesumptionem, which means "confidence or audacity."
