Quietly he accepts a pay increase, the hypocrite (8)
I believe the answer is:
pharisee
'the hypocrite' is the definition.
(thesaurus)
'quietly he accepts a pay increase' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'accepts' is an insertion indicator.
'pay increase' becomes 'rise' (I've seen this before).
'a'+'rise'='arise'
'he' going around 'arise' is 'harisee'.
'p'+'harisee'='PHARISEE'
(Other definitions for pharisee that I've seen before include "A Biblical hypocrite" , "scribe's partner" , "Hare pies for the Biblical pedant" , "Member of ancient Jewish sect; Heap, sire (anag.)" , "Strict observer" .)
