put on your hauberk and whip out your vocabulary

Thanks to Jonathan Lill, previous Williamsburg Spelling Bee winner, for the tip:

FreeRice.com is a vocabulary quiz website through which companies donate ten grains of rice to famine-stricken areas for each word you get correct.

I played on and off all day and donated some 2,770 grains of rice. Not sure how much rice that is, in practical terms.

In any case, the test is adaptive, so if you are a sesquipedalian sort, the game isn't boring; you quickly progress to much harder words -- especially, it seems, a great many nouns naming specific medieval objects. Hence the title of this post.
