Common Abbreviations and Acronyms اختصارات انجليزية مشهورة 

Here are some of the most common abbreviations and acronyms used in English language. 


Light Amplification by Stimulated Emission of Radiation
Laser has eclipsed its identity as an acronym at this point; it’s now treated as a word rather than an acronym. Its origin as an acronym is still fairly common knowledge, but who among us can remember what it actually represents? So now it’s time to commit it to memory: Light Amplification by Stimulated Emission of Radiation.  


 Radio Detection And Ranging
Radar: another technology named by initials. Like laser, we no longer treat radar like an acronym. Unlike laser, radar stands for a combination of words even us non-scientists can probably remember: Radio Detection And Ranging. You got this.

ZIP code

 Zone Improvement Plan
In the U.K. and Australia, they’re known as postcodes. In Canada, postal codes. So why does the U.S. have a bizarre term like ZIP code for the string of numbers that allows mail services to direct our correspondence more efficiently? The answer, of course, is that it’s an acronym for Zone Improvement Plan, referring to the U.S. Postal Service’s scheme for improving their mail delivery codes. The zippiness of the term is just a bonus. (When the new codes first launched, USPS even advertised the codes with a goofy cartoon named Mr. Zip.)


 Special Weapons And Tactics
This seems pretty obvious, but in case you need an ice breaker the next time a SWAT team breaks into your house by accident during a botched drug raid... now you know!


 Before Anyone Else
Bae sounds really similar to the more time-tested endearment “babe,” but reportedly it’s also an acronym.
