Things to know about the words you learn

Usually the first things you learn about a new English word are what it means and its translation in your own language. But there are other things you need to find out before you can say that you know a word like a native speaker does. For example, you have to learn:

• how it is spelled
• how it is pronounced
• how it is inflected (i.e. how it changes if it is a verb, noun or adjective)
• other grammar information about it
• how it collocates (i.e. what other words are often used with it)
  
• if it has a particular style or register
• the context in which it is most likely to be used 

Native speakers learn these things about words by hearing them and reading them again and again. This is the best way for you to learn them, too.
