A great site I have been visiting is Declan’s Audio Word of the Day. They currently have a Word of the Day in 11 different languages. I usually listen to the Arabic one (because I am taking Arabic), the Spanish one (to improve my bad Spanish) and the Italian Word of the Day (because I have always wanted to learn and visit Italy). So instead of visiting their webpage every day, I figured it would be easier to add in a widget for the ones that like.
Their website is http://www.hitsalive.com/wordoftheday/ . They also sell language software and have applications for iPhones.
