Chapel area in gold colour with blue? (7)
I believe the answer is:
oratory
'chapel' is the definition.
(an oratory is a small chapel)
'area in gold colour with blue?' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'in' is an insertion indicator.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'colour with blue?' becomes 'Tory' (Tory blue is a colour).
'or'+'tory'='ortory'
'a' put inside 'ortory' is 'ORATORY'.
(Other definitions for oratory that I've seen before include "Art of speech" , "Place for private prayer" , "Cicero's art" , "Public speaking - eloquence" , "Gift of the gab" .)
