Developing an idea in writing involves expanding upon a thought or argument, which allows the writer to provide depth and complexity to their main points. This process includes elaborating on the idea, providing evidence or examples, and exploring different facets of the thought being presented.

Through expansion, the writer can clarify their message, persuade the audience, and create a more nuanced discussion. Providing a brief overview, offering a simple definition, or contrasting another idea does not fully capture the process of developing an idea, which requires a more detailed and thorough approach.
