I used to believe "foyer" meant fireplace because is german feuer [pronounced like foyer] means fire.
I never heard anyone say foyer before, until i was at my grandmas house once. She told me to go wait in the ''foyer'', and i had no idea what she was talking about. I thought she wanted me to wait in the fireplace!!
