Important Abbreviation & Acronym List in English You Should Learn

Sharing is caring!

Abbreviation! Acronyms! Following is a full list of important abbreviations and acronyms in English you should learn to expand your vocabulary.

Abbreviations vs Acronyms

Abbreviation and Acronym are similar to each other as they both are short forms of longer words; however, they are two different parts of the English language.

An abbreviation is a shortened version of one or two words which are still pronounced the same way, even if they are written as an abbreviation.

An acronym, on the other hand, is a shortened version of the phrase that is most often the name of something. They are pronounced as their short forms rather than their actual full form.

NATO is pronounced NAY-TOE and not as North Atlantic Treaty Organization. Acronyms are also pronounced by the individual alphabet like with U.N, FBI, etc.

I strongly disagree with the meaning of the acronym, 'NASA'. Officially it stands for; National Aeronautics and Space Administration But reality suggests a very different meaning indeed, and it works much better for me that way, because it says exactly what its function is, unmistakably; (N)ever (A) (S)traight (A)nswer.
