Fifth-rate (4)
I believe the answer is:
poor
'fifth-rate' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for poor that I've seen before include "Having little money and few possessions" , "Impecunious; wretched" , "Badly off - inferior in quality" , "Of low quality" , "They used to have a law" .)
