What function does a signpost serve in writing?

A signpost in writing serves to indicate the direction of the argument. This means that it helps guide the reader through the structure and flow of the text, signaling shifts in the argument or transitions between different sections. By using signposts, a writer clarifies the relationship between ideas and enhances the overall coherence of the piece, making it easier for the reader to follow the progression of thought.

Navigating through complex discussions or arguments becomes more manageable for the reader when signposts clearly indicate what to expect. This function is crucial in persuasive writing or any form of argumentative text, where clarity and logical flow are essential for effectively communicating the writer's message.
