Stuff given to priest for pain? (5)
I believe the answer is:
cramp
'pain?' is the definition.
(thesaurus)
'stuff given to priest' is the wordplay.
'stuff' becomes 'cram' (cramming is a kind of stuffing**).
'given to' is a charade indicator (letters next to each other).
'priest' becomes 'p' (ecclesiastical abbreviation).
'cram'+'p'='CRAMP'
'for' is the link.
(Other definitions for cramp that I've seen before include "Severe muscular pain" , "restraint" , "Give too little space to" , "Form of muscular pain" , "common among writers" .)
