Hi, I have been really very weak at my vocabulary power and I usually got stuck on mere words. But now thanks to the oxford advance learner's dictionary I have improved alot as you can see from my writing. It's a great flatform to improve your English within no time and without any teacher or any personal tutor. Easy to use amd easy to get. It happens always that we get stuck when we are reading a novel or a short article and do not understand the actual meaning of the particular thing due to weak vocabulary. But not to worry as Oxford advanced learner's dictionary is the right thing that will help you
