Among the Lozi of Zambia, Max Gluckman discovered a culture focused on debates with a rich vocabulary to describe the quality (or lack thereof) of someone’s argumentation:
kuyungula —to speak on matters without coming to the point
kunjongoloka —to wander away from the subject when speaking
kubulela siweko —to talk without understanding
muyauluki —a judge who speaks without touching on the important points at issue
siswasiwa —a person who gets entangled in words
siyambutuki —a talker at random
