Words for Hunger

For all you vocabulary fans: FreeRice.com

For every correct word chosen from a four-word multiple choice list, FreeRice.com will donate 10 rice grains to the United Nations World Food Program. So far 232.7 million grains have been donated and the site only began on October 7. I earned 1000 grains tonight.

The site itself is gorgeous and they customize your test as you answer the questions. Read the FAQ for a description of how it works. I fluctuated around the mid- to low 40s. How 'bout you?

Here are some of the more difficult words I got (descriptions in the comments):

teredo
hebdomadal
meretricious
amercement
leister
rumen
