discourse

Picture a Roman speaker who is literally running circles around a topic. That is the hidden little theater inside discourse: dis- means apart, currere means to run, and the original Latin discurrere suggested moving to and fro before it ever suggested elegant prose. By the time French took over as discours and English borrowed it in the late 1300s, the word had slowed down from actual motion into something much more civilized: talking, reasoning, laying out an argument. It even shares a family resemblance with discuss, which began life as "shake apart" before turning into "analyze," and with course, the idea of a path or movement that somehow became the path of an argument. No wonder modern internet users now say "the discourse" when they mean the whole frantic online swirl of takes, replies, and hot-thought collisions—the word has come full circle without ever really standing still.
