How to learn vocabulary effectively?

Language is one of the biggest barriers of international students in integrating to the new environment. And vocabulary is one of the most important things in learning a new foreign language beside grammar, listening, and speaking as you cannot communicate with foreigners if you don’t know the words. In fact, there are a lot of ways to learn vocabulary.
Many people learn new words by writing them on pieces of paper and sticking them everywhere in the house. By doing it, the words appear many times in front of them, and they remember the words unconsciously.
Some other people improve their vocabulary by reading news, novels, and fictions. On one hand, they can update information as well as know more about history, economics or about other countries’ cultures depending on the kind of book they read. On the other hand, they can learn new words and the way words are put in specific context. It is more effective than just learn the words separately.
Another very interesting way to learn vocabulary is through listening to the music or watching movies. When you love the song, you can sing it and remember its words more easily and effectively than holding a notebook and studying word by word. Moreover, by listening music or watching movies, you can also improve your listening skill.
Actually, every person may have different learning methods that best suit him. Depending on your strengths, your hobbies you can choose the most effective method for you.
