Etymology
the word 'discussant' is a modern english formation, directly combining the verb 'discuss' with the agentive suffix '-ant'. the verb 'discuss' itself originates from latin discutere, composed of dis- ('apart') and quatere ('to shake'), conveying the literal sense of 'to shake apart' or 'break up'. this physical meaning evolved metaphorically into 'to examine or debate an issue by breaking it down into its parts'. the suffix '-ant', of latin origin via french, is used to form nouns indicating a person who performs a specific action. therefore, a 'discussant' is logically one who engages in the action of breaking down and examining a topic through conversation.
