English Abbreviations: Their Meaning, Function and Frequent Examples

If there's one type of vocabulary you'll continually learn in English, it's the abbreviation (a shortened form of a word or phrase, typically two to four letters long).

People use hundreds of English abbreviations daily, in both formal professional situations and informal casual ones. New abbreviations can appear every week or month.

Here is a simple guide to understand how abbreviations function and to learn some of the most common ones you should know.

How Do Abbreviations Work in English?

Abbreviations can represent a single word or a group of words.

They are formed by taking the first and/or last letters of a word, or the initial letter of each word in a phrase.

For example:

• Miste r = Mr.
• I nternational B usiness M achines Corporation = IBM

Certain abbreviations conclude with a period (.), while others do not. A period can sometimes indicate that you are using an abbreviation and not a complete word, but it is not always necessary.

However, when an abbreviation does end with a period, it doesn't necessarily signal the start of a new sentence.

The period is simply a component of the abbreviation that clarifies it is a shortened form.

There is also a category known as an acronym, which is a specific kind of abbreviation. Acronyms are created specifically from phrases, formed from the initials (the first letters of the words) in that phrase.

An abbreviation like IBM might be considered an acronym, but typically, acronyms are pronounced as a single word.

For example:

• National Aeronautics and Space Administration = NASA , pronounced “na-suh” and not “en-ay-ess-ay”
• Radio detection and ranging = RADAR , pronounced “ray-dar” and not “ar-ay-dee-ay-ar”

Most Common English Abbreviations

These abbreviations are used constantly. It's likely you'll encounter or hear some of them at least once a day.

3. Mrs. — Missus

To address a woman who is older or married in a polite or respectful manner, you would use “Missus (name).”
