Answer: The term that best describes the prewriting process is Idea Generating.
Step-by-step explanation:
The prewriting process is where you organize your ideas, make a plan for your writing or study, and make sure your thesis is clear.
Prewriting allows you to think of what and how you want to write based on the overall topic (so it wouldn't be aimless). However this doesn't mean that it needs to be rigid (not able to be changed) as you can change your ideas if it doesn't seem right to you. Also prewriting is informal, meaning to have relaxed/unofficial manner. Your prewriting process is what you make of it, as you create various of ideas that you would use in your writing.
