A disputant or debater, someone skilled in philosophical or rhetorical argument. Paul uses this term in 1 Corinthians 1:20 when asking "Where is the debater of this age?" The word emphasizes intellectual contestation rather than simple disagreement—this is someone who makes a practice of challenging ideas through formal disputation. The multilingual glosses (Spanish 'debatidor', French 'discuteur', German 'Disputierer') all capture this sense of active, skilled argumentation.
