In the world of business, acronyms and abbreviations are commonplace. There are literally hundreds and hundreds of these acronyms and abbreviations are in use, and quite a few of them have more than one meaning, depending on the business context or, even, depending on internal company usage.

No wonder then that many people loathe them. However, the fact remains that they are constantly employed and learners of English will inevitably come across many of them in the course of their work.

If there are so many, how can you remember them? The truth is, it is almost impossible to remember all of them (perhaps only a word enthusiast would memorise every single one of them). Nonetheless, you should try to remember the ones which are the most important and most common in your area of expertise.

To help learners of business English, here’s a collection of the most important and most commonly used business acronyms and abbreviations.
