Many students studying English tell me that they understand everything when they are in their English lessons. But when it comes to watching English TV programs or movies or chatting with native English speakers, they struggle to understand what people are saying. Many factors can cause this, such as the speed at which speakers are talking or their accents. Also, in reality, native speakers shorten words and use English abbreviations a lot. So learning common abbreviations in English can be a helpful way to improve your comprehension. Keep reading until the end to learn the most common English language abbreviations…


🇺🇸 30 Common English Abbreviations 🇬🇧

The following shortened English words are so commonly used that dictionaries list many of them without stating that they are abbreviations. Some are even used more frequently (especially in spoken English) than the original, full word.

When to use English abbreviations?

Sometimes it can be hard to know when it is appropriate to use these “shortcut words” in English. Many of the abbreviations on this list are so common that they can be used any time, including professional or formal situations. Most native speakers use additional abbreviations among friends, family, and peers. Sometimes these are not appropriate for professional use.

To help clarify what can sometimes be a tricky subject, we’ve split this list into two categories: English abbreviations that you can use in any context, and those that should be limited to casual situations among family and friends.

That covers when to use these abbreviations. For each shortened word in English on this list, we also give you a few examples of how to use it.
