Talk about the French holiday home (6)
I believe the answer is:
chalet
'holiday home' is the definition.
(I've seen this before)
'talk about the french' is the wordplay.
'talk' becomes 'chat' (I've seen this before).
'about' means one lot of letters goes inside another.
'the french' becomes 'le'.
'chat' enclosing 'le' is 'CHALET'.
(Other definitions for chalet that I've seen before include "Originally an alpine cowherd's hut" , "A Swiss mountain cottage" , "Swiss cottage or small villa" , "Swiss hut or cottage" , "Swiss holiday home" .)
