French art gallery's windows? (7)
I believe the answer is:
louvres
'french art gallery's windows?' is the definition.
I can't judge whether this definition defines the answer.
'gallery's windows?' is the wordplay.
'gallery' becomes 'louvre' (I've seen this before).
'windows?' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'louvre'+'s'='LOUVRES'
Can you help me to learn more?
(Other definitions for louvres that I've seen before include "Slats" , "series of flaps" .)
