Q:
Where does the Russian word сундук (soondúk = trunk, chest, as in treasure chest) come from?
A:
It's probably from Arabic صَنْدُوْق (Sanduuq = box, bin, money box, fund)! I would guess it came into Arabic from Persian (it's not at all a typical Arabic word, and resembles other Persian loanwords).
Here's a screen grab from the trailer for the upcoming movie You Don't Mess with the Zohan, apparently about a Mossad agent turned NYC hair stylist who runs into some friends from his terrorist-fighting days.
See anything wrong with it? Besides the guy's unusual hairstyle — all the Arabic text is backwards.
