rag
'scrap of cloth' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rag that I've seen before include "Scrap; one lost by the angry" , "Tattered cloth or university fiesta" , "Play practical jokes on - worthless newspaper" , "A tattered cloth or university frolic" , "Cloth; bait" .)
