"Truth is one; the sages just speak of it in different ways."
Getting off the Brooklyn Bridge today, I saw a sign, in fading paint, on the wall of a building: "Flats to let / So-and-so Realty." Were "flats" and "to let" really once common American lingo? If so, when? And what process banished them from our vocabulary? (I had an English friend vigorously complain to me one pub night that contemporary American English does not distinguish between the function of a landlord, who in England has a flat "to let," and that of a potential tenant, who wishes "to rent" that flat.)
