Polyglot - It basically renders selected words on websites you visit in a language you choose.

Don't know what the translated word is? Hover over it and it will show you the English translation.

I installed this extension today and it found it a pretty helpful refresher / learning tool.

Install it on Chrome, edit your options, pick the language you'd like to learn/refresh, and you can even set filters on which words are translated.
