Academic writing doesn't have a single definition. You'll see forms of it in different areas of academia and research. The goal stays the same - to prove a theory or hypothesis. Writers dissect ideas, question reasoning, and support conclusions.
Academic writing differs from other forms of writing, but it also has commonalities. Many forms are commentaries on specific topics, and they give an analysis or opinion. Academic writing, though, looks at a topic from an impersonal, research-driven angle.
