Miserable, being second-rate (4)
I believe the answer is:
poor
I believe this is a double definition.
'miserable' is the first definition.
(synonyms)
'second-rate' is the second definition.
(synonyms)
'being' is the link.
(Other definitions for poor that I've seen before include "Unsatisfactory or in need" , "Of inferior quality or means" , "Lacking money and resources" , "Of low standard" , "Impecunious; wretched" .)
