10 Prefixes That Will Dramatically Improve Your Vocabulary

Although my mother tongue is English, there are still a ton of words that I don’t know. Many of these English words are technical or related to an unfamiliar topic, like geology, chemistry, or computer engineering. When I come across one of those words, I can often guess the meaning.

 

Sometimes, I rely on the context. I ask myself, "What do I know about the situation that can help me decode this new word?" Or "Is the speaker happy, sad, tired, or disappointed?"

 

Other times, there is a part of the word that has a specific meaning that helps me get to the essence of the word. Like, if I see “photo” in a word, I know it’s going be related to light: photograph, photosynthesis, photon.

 

You can do the same!

 

In today’s top ten list, I’m going to give you ten commonly used word beginnings, called prefixes, that have very specific meanings. These little guys are special keys that can unlock the mysteries of vocabulary that you already know, and even better, allow you to quickly understand new words that you’re going to see in daily life.
