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'm unsure of the 'religious' bit.
'doctor's brought to that french' is the wordplay.
'doctor's' becomes 'mo's' (medical officer).
'brought to' says to put 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" .)
