ACRONYMS

An acronym was originally a pronounceable word made from the initial letters of other words. For example, NATO for the North Atlantic Treaty Organization.
As acronyms have invaded our lives more and more we have started to coin other shorthand versions such as TV for Television, USA for United States of America, IOU for I Owe You (a debt), MD for Medical Doctor, or CEO for Chief Executive Officer which are not acronyms in the original sense of being a ‘new pronounceable word’ made up of the first letters but which we still pull into our bulging bag of acronyms.

But where acronyms have really exploded and become a sub-language of their own is through text messaging, the Internet and email where the ‘need for speed’ has led to the creation of hundreds of new acronyms that are used globally by millions of people. Your example, LOL for ‘Laugh Out Loud’ is one of the most used of these Internet acronyms. Here is a list of some of the other common Internet acronyms used in emails, SMS and text messaging. Hope it helps, CU!
