Writing can be categorized into different modes such as narrative, informative, and persuasive. The types of writing are extensive writing, where the writer is given a broad topic, and intensive writing, where the topic is more focused. The writing process involves several steps: prewriting, drafting, revising, editing, and publishing. Qualities of good writing include having interesting ideas, clear organization, an engaging voice, precise word choice, varied sentence structures, and correct grammar conventions.
