While necessary, jargon is the final type of business English you will
learn. Before learning jargon you should first focus on general business
English. Master the most common business phrases by listening to and
reading real business content. Only after you have done this should you
concern yourself with jargon.
Of course, you’ll learn your field’s jargon in exactly the same way as you
learned general business English. When you are ready, simply change the
material you are listening to and reading. Gather real materials that are
specifically related to your field.
Choose material that is useful. Rather than focusing on the English, focus
on learning more about your field from English sources. Develop your
knowledge and skills using these sources and you’ll automatically improve
your business English at the same time.
