“it’s the put-er-on-er-er”
When I was brought up in England we used to say things like “it’s the put-er-on-er-er” for the brush used to put the polish on, and the “taker-off-er-er”. Or later, the “mover-out-er-er” for the spouse who must move out.
Is this “real” English? Why don’t we use it in writing? Why are there two “er” at the end? Is there any description of this in any grammar? How widespread is this construction?
