1702 Room for Approval

In reply to my commentary about naming rooms I got some interesting feedback from my friend Rick. I'd noticed that we often name our rooms for their purpose—bathroom, bedroom, living room—and yet we had certain words that didn't follow the pattern, like kitchen, den, foyer, and so on.
Kitchen I get, as it derives from a German word for cooking, and den is like the original room from our bearly primitive domiciles so it's great-grandfathered in, but foyer? I hardly know her. How does one foy anyhow?
Rick commented on the term "utility room." Aren't all rooms of some utility? Certainly we expect our rooms to be useful at a bare minimum. Maybe it's to distinguish it from that one non-utility room—the pristine white "Formal Living Room" you see in some places.
The there's the "Bonus Room." Is that where you go if you score? Maybe it's where you store all your comp cards from the casino. Rick thought Napoleon may have had a "Great Room" or two. I'm thinking he did a lot of his plotting in the Throne Room.
Rick also pointed out one of those great room conundrums. Why does a half bath not have a tub at all? Just a toilet and a sink. He suggested we combine those words and coin the name "tink." I'm in favor of "soilet". Makes more sense in some of the bachelor pad half baths I've been to. Not the kind of throne rooms you'd like to crown with the Good Housekeeping seal of approval.
Come to think of it, if he's anything like the ones in the Sound, I rather not have him waddling through any of my rooms. The good housekeeping seal had darn well better be house trained.
America ya gotta love it.
