Crush a Muslim dignitary (5)
I believe the answer is:
pasha
'muslim dignitary' is the definition.
(I've seen this before)
'crush a' is the wordplay.
'crush' becomes 'pash' (I can't explain this - if you can you should give a lot more credence to this answer).
'pash'+'a'='PASHA'
Can you help me to learn more?
(Other definitions for pasha that I've seen before include "Ottoman governor" , "foreign officer" , "Civil or military authority in Turkey or Egypt" , "Turkish high-ranker" , "Muslim dignitary" .)
