Important Abbreviation & Acronym List in English

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. Following is a full list of important abbreviations and acronyms in English.

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.
