He preaches equality before a member of the younger generation (6)
I believe the answer is:
parson
'he preaches equality before a member of the younger generation' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he preaches equality' is the wordplay.
I cannot quite see how this works, but
'he' could be 'son' and 'son' is found in the answer.
'equality' could be 'par' (synonyms) and 'par' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for parson that I've seen before include "Churchman" , "A rector or vicar" , "One with benefice" , "man of the church" , "service provider" .)
