I thought it would never happen, but it did. Lynne Murphy has alerted me that the American site Slate has published the following sentence. (It’s from the Dear Prudence advice column; a woman has written in complaining that all her friends want to talk about is their darling baby grandchildren.)
Let’s hope these two can get free from the nappies long enough to come to brunch at your house or join you somewhere for coffee.
There is no reason for no reason for an American writing for an American publication to use “nappies” instead of “diapers”–other than being cute, that is. There’s nothing wrong with being cute, of course, but I would be gobsmacked if “nappies” caught on here.
