hi
here is some way to try:
1-watch film. start with you favorit films and watch it several times don't check the new word during the film.
2-if you feel the new word that you want to learn is hard for you or you think that you are not ready to use it in a sentence so let the word go, don't worry about that, be sure that one day it'll come back and that day you are ready.
3-read and listen so much and don't worry about the new word. just read and listen.
4- try lietner learn box. it's good for just some case. learn hard words with this.
