Prayer leader: you can call me a leader of Muslims (4)
I believe the answer is:
imam
'prayer leader' is the definition.
(I've seen this before)
'can call me a leader of muslims' is the wordplay.
'can' is an anagram indicator (I've seen 'canned' mean this (canned can mean drunk)).
'call' indicates a 'sounds like' (homophone) clue.
'leader of' says to take the initial letters.
The first letter of 'muslims' is 'm'.
'me' is a homophone of 'mi'.
'mi' with letters rearranged gives 'im'.
'im'+'a'+'m'='IMAM'
'you' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for imam that I've seen before include "Muslim preacher" , "Islamic minister" , "Caliph" , "Islamic prayer leader" , "Leader of prayers in mosque" .)
