Distinctive character is only a priest perhaps (11)
I believe the answer is:
personality
'distinctive character' is the definition.
(I've seen this before)
'only a priest perhaps' is the wordplay.
'perhaps' indicates an anagram.
'only'+'a'+'priest'='onlyapriest'
'onlyapriest' anagrammed gives 'PERSONALITY'.
'is' acts as a link.
(Other definitions for personality that I've seen before include "Charisma" , "Distinctive character" , "Individual character" , "(Distinctness of) character" , "Celebrity" .)
