Word-transposing cleric (7)
I believe the answer is:
spooner
(Other definitions for spooner that I've seen before include "Victorian cleric who "fed sunny things"" , "One who gave his name to a transposition of sounds in speech" , "Initial-transposing clergyman" , "Revd W.A.- was famed for his errors in speech" , "Tongue-tied man" .)
