One putting up English clergyman (7)
I believe the answer is:
erector
'one putting up' is the definition.
The definition suggests a singular noun which matches the answer.
'english clergyman' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'clergyman' becomes 'rector' (rector is a kind of clergyman).
'e'+'rector'='ERECTOR'
Can you help me to learn more?
(Other definitions for erector that I've seen before include "Builder" , "The individual raising" , "One who puts (something) up" , "Muscle" , "puts things up" .)
