Aprons designed for clergyman (6)
I believe the answer is:
parson
'for clergyman' is the definition.
(parson is a kind of clergyman)
'aprons designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'aprons' is an anagram of 'PARSON'.
(Other definitions for parson that I've seen before include "man of the church" , "Rector; clergyman" , "service provider" , "Churchman" , "Minister of religion" .)
