Hello :)

I'm a Korean learner and I need a bit of advice. It is very hard for me to learn new words as I somehow cannot find any books that are focused on vocabulary itself - I have plenty of grammar books, but not as much books with new words.

Could you please recommend me some books that focus on new vocabulary? The best would be if the words are listed according to topics (human body, fruits, colours, human character, means of transport etc..)

Thank you! :)
