Creative writing involves using imagination and invention in both form and content. It includes fiction, poetry, and drama in various formats like long or short stories, different poetry forms, and works for stage, movies or television. Creative writing uses made-up materials and aims to please readers aesthetically by engaging their imagination rather than just conveying facts. While some works are lightly entertaining, others can reveal profound truths about human nature and experience. The main types of writing are fiction and non-fiction, technical and popular, and formal and informal styles.
