A person or thing that engages in interaction with others.
In a group discussion, each interactant contributes their ideas and opinions.
Interactant → It is formed from "inter-" (meaning between) and "actant" (from Latin "agere", meaning to do or act). The word describes a participant who acts or engages in an interaction between parties.
Think of someone who is 'acting' ('actant') 'between' ('inter-') others — that's why an interactant is someone who engages in an interaction.
