I'm having an odd experience with this - a rapid start, with quite a lot much easier than usual with this setter. However I've got several entries I don't fully understand, and I've ground to a halt in the SE. Could I have a hint for this one, please? (I've chosen this as the letters placed are definitely right!)

I suspect that "chap" might be a verb form, but I still don't get anything apart from the initial R.
