You can help end world hunger by playing on freerice.com. For each word you guess right, the website will donate 10 grains of rice to the United Nations to end world hunger.

After you have done FreeRice for a couple of days, you may notice an odd phenomenon. Words that you have never consciously used before will begin to pop into your head while you are speaking or writing. You will feel yourself using and knowing more words.

So simple.
