First person is bringing parent over to see man who leads prayers (4)
I believe the answer is:
imam
'first person is bringing parent over to see man who leads prayers' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'first person is bringing parent over to see man' is the wordplay.
'first person' becomes 'I' (first-person pronoun).
'is bringing' says to put letters next to each other.
'parent' becomes 'ma' (ma can mean mum or mother).
'over' means one lot of letters go next to another (in a down clue, some letters go over others).
'to see man' becomes 'm' (M is an abbreviation for male or masculine).
'i'+'ma'+'m'='IMAM'
Can you help me to learn more?
(Other definitions for imam that I've seen before include "Muslim prayer leader" , "Muslim preacher" , "Maim (anag)" , "Person leading devotions in a mosque" , "Islamic prayer leader" .)
