Tonight we were eating spaghetti. We got out the parmesan cheese and a debate began between Heulwen and Ella. Yes, they can get into it about literally anything.
Ella, who can read, said it was "parmesan cheese". Heulwen, who is not quite literate yet, declared that it was "Farmers an' Cheese". (Ew.)
"Heulwen," I said, "that's folk etymology."-- not thinking she was listening at all. Why would she?
A triumphant cry burst from her corner: YAAAY!!! FOLK ETYMOLOGY!!!"
I guess, for her, that inkhorn term settled it. Heulwen one, Ella nil.
