A. WordFind is a great app for English language learners, especially when you are studying alone. Our teacher told us about it in class. He said he uses it all the time, so I decided to try it. Last week I downloaded it on my phone and I love it!
B. It's good because the definitions are very easy to understand. It tells you what each word means in simple English, and how and when you can use it. You can also search for a word by saying it. I can't always find a word I'm looking for when I don't know how to spell it, so this is very useful.
C. In my opinion, there are a couple of problems with it. It tells you where each word comes from and when people first used it, but I'm not interested in the history of words. Also, it's expensive - there are lots of free dictionary apps, though maybe they're not as good.
D. Overall, I think WordFind is a great app because you can use it anywhere and it's easy to use. I would definitely recommend it.
