Discursive writing or speaking wanders from topic to topic rather than staying tightly focused on one main point. Think of the difference between a train following straight tracks to its destination and a meandering river that curves and loops through the countryside. Discursive communication is like that river: it explores side paths, makes unexpected connections, and takes its time getting where it's going.

A discursive essay might start by discussing your favorite book, drift into memories of your grandmother's stories, consider what makes a good storyteller, and eventually circle back to why that book matters to you. The ideas connect, but not in the most direct way possible. Some teachers prefer tightly organized, point-by-point writing, while others appreciate a more discursive style that lets ideas breathe and connect naturally.

While discursive can sometimes suggest rambling without purpose, it also describes a thoughtful, exploratory way of thinking through ideas. Scientists writing discursive papers might examine a question from multiple angles before reaching their conclusion. A discursive conversation with a friend might jump between topics but still feel meaningful and connected. The opposite would be writing or speaking that marches straight to the point without any scenic detours along the way.
