Converse about the French holiday home (6)
I believe the answer is:
chalet
'holiday home' is the definition.
(a building within a holiday resort)
'converse about the french' is the wordplay.
'converse' becomes 'chat' (chatting is a kind of conversing).
'about' means one lot of letters goes inside another.
'the french' becomes 'le' ('the' in French).
'chat' enclosing 'le' is 'CHALET'.
(Other definitions for chalet that I've seen before include "Small hut in holiday camp" , "Wooden house with projecting eaves" , "holiday accommodation" , "Wooden house of Alpine regions" , "The lac (anag.)" .)
