Hi,
There are lots of ways to learn new words; READING to see them in context, word puzzles, pasting them where you'll see them, flashcards, etc.
I suggest you look through the pages of other questions as other people have asked a similar question and many good answers have been given.
Look for key words such as 'English words', 'vocabulary', 'remembering' in the question titles and I'm sure you'll find them. I know for sure there was one two days ago and I think before that as well.
Cheers!
