My memory is too weak to learn like juwita suggests. I'm not as smart as she is. I find that taking some words and using them in sentences is helpful. Then I use them in conversation, like on italki. I also read passages that contain words that are at my level and use them in reading and talking. After I've used the words a while, they become a part of me. As time goes on and I feel more comfortable, I add more words.

1st day, write 5 new vocabs then memorize it.........the next day, u write 5 new vocabs again....then memorize it together with your vocabs in the day before......so you'll get 10 vocabs in 2 days.........just do it continually.......every day you have to write 5 new vocabs then memorize it with your old vocabs..... wish it would be effective...:)

you can also try watching movies, English movies. while doing so,write all those words that aren't familiar to you. after the movie, try to look for their meanings in a dictionary. analyze,then try to write a sample sentence using the words. you may also look for a partner and have a dialogue with each other using some of the words you've written down. that'll help a lot.

I think reading books is the most effective way. It allows you to understand the meaning along with its correct usage and spelling.

My son uses LearnThatWord.org to study vocabulary, it is fast and easy way to learn new words.
