Playful university teacher hugging almost every clergyman (10)
I believe the answer is:
archdeacon
'clergyman' is the definition.
(I know that archdeacon is a type of clergyman)
'playful university teacher hugging almost every' is the wordplay.
'playful university' becomes 'arch' (I am not sure about this - if you are sure you should believe this answer much more).
'teacher' becomes 'don' (don is a kind of teacher).
'hugging' is an insertion indicator.
'almost' means to remove the last letter (most of the word but not all of it).
'every' becomes 'each' (synonyms).
'each' with its final letter removed is 'eac'.
'don' enclosing 'eac' is 'deacon'.
'arch'+'deacon'='ARCHDEACON'
Can you help me to learn more?
(Other definitions for archdeacon that I've seen before include "Senior Christian cleric" , "ecclesiastical dignitary" , "Church official" , "Member of clergy" , "Church dignitary" .)
