A person who argues or disputes frequently; someone engaged in debate or controversy.
From Medieval Latin disputator, agent noun from disputare (to dispute). The -or suffix creates an agent noun meaning 'one who disputes.'
In medieval universities, disputatores were formal debaters—arguing wasn't a sign of rudeness but a form of rigorous education! Scholastic scholars would have formal disputations where masters and students would argue points of logic and theology for hours.
