Kiosk
As part of my drive for proficiency in Greek, I read the road signs and noticed how often 'kiosk' appears, even as the name of stores.
Asked the brainies if it was derived from Greek and and no one knew:
[French kiosque, from Turkish köşk, from Middle Persian gōshak, corner, from Avestan *gaoshaka-, diminutive of gaosha-, ear.]
WORD HISTORY : The lowly kiosk where newspapers are sold or advertisements are posted is like a child in a fairy tale raised by humble parents but descended from kings. The word kiosk was originally taken into English from Turkish, in which its source köşk meant “pavilion.”
