I use Google's Definition feature sometimes. Until now, I've only used it when searching for English definitions. However, I just discovered it has definitions in other languages as well. I've never seen it before, so they have either just added it (I saw it yesterday) or for some reason, I didn't notice it before.
Here is an example. If you look at the bottom, you can see it will also give you the definition of that word in other languages.
