Muslim official's snores interrupting an arrangement of unfinished minuet (7)
I believe the answer is:
muezzin
'muslim official's' is the definition.
(I've seen this before)
'snores interrupting an arrangement of unfinished minuet' is the wordplay.
'snores' becomes 'zz' (I can't explain this - if you can you should give a lot more credence to this answer).
'interrupting' is an insertion indicator.
'an arrangement of' indicates an anagram.
'unfinished' means to remove the last letter.
'minuet' with its final letter removed is 'minue'.
'minue' anagrammed gives 'muein'.
'zz' inserted inside 'muein' is 'MUEZZIN'.
Can you help me to learn more?
(Other definitions for muezzin that I've seen before include "He calls the faithful to prayer" , "Muslim prayer caller" , "Mosque official caller" , "He proclaims the hours of prayer from 23 Across" , "Minaret crier" .)
