Abstract:

Business English (BE) and business communication (BC) overlap. English handles linguistic mechanics and style, whereas communication holistically discusses the movement of a message from one person to another. The BC discipline, unfortunately, allows language basics into its pedagogy like a statistics course teaching fundamental mathematics. From the other side, some English courses teach BC before their students are able to handle that material. A subject teaches prepared students. If they are deficient, they are either kept out or the subject matter suffers.
