Difficult to get credit, one broke (9)
I believe the answer is:
recondite
'difficult' is the definition.
(thesaurus)
'get credit one broke' is the wordplay.
'get' means one lot of letters go next to another.
'broke' indicates anagramming the letters.
'credit' put next to 'one' is 'creditone'.
'creditone' anagrammed gives 'RECONDITE'.
'to' acts as a link.
(Other definitions for recondite that I've seen before include "Abstruse" , "not widely known" , "(Of knowledge) obscure" , "Direct one to be obscure or difficult" , "Difficult to understand" .)
