The offscouring of society, or rather, “refuse and sweepings.” Rief is Anglo-Saxon, and means a rag; Raff is also Anglo-Saxon, and means sweepings. (Danish, rips-raps.) The French have the expression “Avoir rifle et rafle,” meaning to have everything; whence radoux (one who has everything), and the phrase “Il n'a laissé ni rif ni raf” (he has left nothing behind him).
“I have neither ryff nor ruff [rag to cover me nor roof over my head].” —
Ilka man agayne his gud he gaffe That he had tane with ryfe and raffe.
Quoted by Halliwell in his Archaic Dictionary.
