+100 Business Acronyms That You Will Need At Work



Slack messages and emails are getting shorter and –sometimes– more difficult to decipher. The thing is, we all have busy lives and the pace of work is too fast. That’s why we come up with strategies to streamline our tasks and speed up communication. In an attempt to find short and simple ways of expressing something, acronyms were created. Explore this helpful list with the most common acronyms you will hear at work and download the cheatsheet below.

What’s An Acronym?

An acronym is an abbreviation formed from the initial letters of other words to create a new, shorter word. NASA, for example, is an acronym that stands for National Aeronautics and Space Administration. Some acronyms are used so frequently that they are now used as regular words (e.g. RADAR – Radio Detection and Ranging or PIN – Personal Identification Number).

If you are wondering how to pronounce acronyms, the answer is –it depends. Many acronyms are pronounce as a regular word (e.g. NASA /ˈnasə/, RADAR /ˈreɪdɑr/, PIN /pɪn/), but others are said by spelling out the individual letters (e.g. BBC /bi bi si/).

Informal Acronyms

Informal acronyms or abbreviations are those used to text friends. However, younger generations have started to use them at work. They are indeed getting more and more common in business communication, mainly on Slack, and especially among the younger sectors and when the speakers already know each other fairly well.

BTW, sometimes your HRM tells you it’s NBD and TYT but TBH they just want that file ASAP by EOD and, you know, ATEOTD, they’re the manager.
