Staff without rupees suffer from hunger (6)
I believe the answer is:
starve
'suffer from hunger' is the definition.
(I've seen this before)
'staff without rupees' is the wordplay.
'staff' becomes 'stave' (synonyms).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'rupees' becomes 'r' (abbreviation for rupees).
'stave' enclosing 'r' is 'STARVE'.
(Other definitions for starve that I've seen before include "Fail to take in" , "Go without food" , "Eat nothing" , "Suffer from lack of food" , "Deprive of sustenance" .)
