Extremely literary head of English at church school in Paris (5)
I believe the answer is:
lycee
'school in paris' is the definition.
'lycee' can be an answer for 'school' (lycee is a kind of school). I'm not sure about the 'in paris' bit.
'extremely literary head of english at church' is the wordplay.
'extremely' means to remove the middle letters (letters on the extremes of the word are used).
'head of' says to take the initial letters.
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'church' becomes 'ce' (abbreviation for Church of England).
'literary' with its centre taken out is 'ly'.
The initial letter of 'english' is 'e'.
'e' put after 'ce' is 'cee'.
'ly'+'cee'='LYCEE'
Can you help me to learn more?
(Another definition for lycee that I've seen is " French state secondary school".)
