Pray here for a Conservative female abandoned (7)
I believe the answer is:
oratory
'pray here' is the definition.
(oratory is a type of chapel)
'for a conservative female abandoned' is the wordplay.
'conservative' becomes 'tory' (informal term for a Conservative Party member).
'female' becomes 'f' (abbreviation).
'abandoned' is a deletion indicator.
'for'+'a'+'tory'='foratory'
'foratory' with 'f' taken away is 'ORATORY'.
(Other definitions for oratory that I've seen before include "Public speaking - eloquence" , "Formal speech-making, could be pompous" , "Art or skill of public speaking" , "Cicero's art" , "Rhetoric - place of prayer" .)
