Study, using various methods. Almost everybody uses vocabulary cards, but to get the most out of them, after you've gone through your stack both ways, go through them again--but this time make up a sentence using each word. An outfit called Audio-Lingual Materials helped me learn spoken German, but the fact that I'd taken Latin first and therefore understood grammar meant I was able to finish three semesters in one and skip a year. If you can find a book like it, or one of their books in your own language and rewrite the exercises for English, you'd do it easily. It's a great method. There's also a method missionaries use, but I forget now what it's called and who puts it out. It can be adapted for learning English. If you belong to a church, call their denominational mission office and ask.

I would go to the top of the page and click on "Find a Language Partner" or click on "Groups" and join one of the many language groups we have. Good luck and hope this helps you.
