Status
Status refers to the writer’s degree of authority and/or power relative to the reader. Are you writing to your boss, to a group of peers, or to someone who is junior to you’? Is your reader a client with whom you intend to continue doing business, or the general public that you can only see from a bird’s eye view’? Are you an expert presenting information to a non-specialist audience, or a novice showing to an authority how much you know about a subject? These features refer to the status of the writer and his writing.
