Books by European authors or simply those set in Europe often mention “vestibule” and “portico” when describing a big house or a building. I never bothered to know what those meant. So now, a vestibule is simply a small room or division between the front door and the main interior. A portico is simply a porch.
Vestibule is familiar to those of us who are Catholic.
What I feel stupid about is a couple of days ago a commercial for the new movie **Whiskey Tango Foxtrot **came on TV and I realized it meant “WTF?” :smack:
