Learn English – Knock me over with a feather


Where does the expression "you could have knocked me over with a feather" come from? My students had never heard it when I used it in class the other day.

Best Answer

knock (someone) down with a feather: to overcome with surprise. This hyperbole dates from the early nineteenth century. An early appearance in print is in William Cobbettt's Rural Rides (1821): "You might have knocked me down with a feather." Today it is more often used with the conditional could (instead of might)

From the Internet Archive: William Cobbet's Rural Rides

I came to a group of shabby houses upon a hill. While the boy was watering his horses, I asked the ostler the name of the place; and, as the old women say, “you might have knocked me down with a feather,” when he said, “Great Bedwin.” The whole of the houses are not intrinsically worth a thousand pounds. There stood a thing out in the middle of the place, about 25 feet long and 15 wide, being a room stuck up on unhewed stone pillars about 10 feet high.

And many thanks to Hugo who found the relevant 1796 excerpt in Porcupine's Works; containing various Writings and Selections, (...) in Twelve Volumes (May 1801)
