'Blanks' is a simple application helping you to learn new English words. It shows you word definition and gives 4 choices as answer. Select one of the choices by dragging it on the hole in the paper. If you are correct, a green hock is displayed. If the selected word does not fit to the definition, you will see a red cross. The word definitions are from Wordnet. The application developer is not associated in any way with Wordnet.
