Shahria, and checks and balances

Article II, Page 2 of the Constitution on display at the National Archives in Washington. (Michael Williamson /The Washington Post)

You have to check out Sasha's Sunday "secret Iranian influence" post if you haven't already. I generally don't nag our readers this way, but this is really cool (okay, my definition of "cool"). Thanks to Arvin Tseng for pointing out the Sharia connection.

Extra bonus question: What word in the U.S. Constitution is indirectly derived from a Persian word? Please verify your answer in a dictionary before offering it; and remember that mere cognates don't qualify—Persian and English are both Indo-European languages and thus have some similarities, but I'm looking for a word that comes into English indirectly from Persian, whether modern or old Persian.
