Lingro

A good way to learn new vocabulary is by reading articles in other languages. If you're a beginner, this can be very time consuming, since a lot of the words you encounter will be new. A great way to make looking up words easier, is by using Lingro. First, find an article on the web in your language of choice, then paste the link into the slot on Lingro to make all words clickable. This will enable you to read the article without having to open another window, or even worse: an actual dictionary. The definition for the word will pop up right on the same screen. It makes practicing a lot easier.
