Doctor’s brought to that French religious building (6)
I believe the answer is:
mosque
'religious building' is the definition.
'mosque' can be an answer for 'building' (mosque is a kind of building). I am not certain of the 'religious' bit.
'doctor's brought to that french' is the wordplay.
'doctor's' becomes 'mo's' (medical officer).
'brought to' is a charade indicator (letters next to each other).
'that french' becomes 'que' (French for 'that').
'mos'+'que'='MOSQUE'
Can you help me to learn more?
(Other definitions for mosque that I've seen before include "Muslim place of worship with minaret" , "Muslim place of prayer" , "Islam prayer house" , "holy place" , "Muslim temple" .)
