Minister’s early life round queen (6)
I believe the answer is:
pastor
'minister's' is the definition.
(synonyms)
'early life round queen' is the wordplay.
'early life' becomes 'past' (someone's past).
'round' becomes 'o' (round can mean a round object).
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'past'+'o'+'r'='PASTOR'
(Other definitions for pastor that I've seen before include "Member of the clergy" , "One with a flock (of people)" , "Church minister" , "A sport (anag)" , "To spar with clergyman" .)
