While we’re being all charitable, here’s a link to FreeRice’s charity vocabulary quiz. It’s pretty simple: They give you odd words, you guess the meanings, and for each word you get right, they donate 10 grains of rice to an international aid agency.
Do you have a large vocabulary? Are you looking for an Internet-based way to waste time? Well, here’s a way to make that work for you.
