Court containing healthy holiday home? (6)
I believe the answer is:
chalet
'holiday home?' is the definition.
(a building within a holiday resort)
'court containing healthy' is the wordplay.
'court' becomes 'ct' (abbreviation used in road names).
'containing' is an insertion indicator.
'healthy' becomes 'hale' (hale can mean fit and healthy).
'ct' enclosing 'hale' is 'CHALET'.
(Other definitions for chalet that I've seen before include "Wooden house with projecting eaves" , "Wooden house of Swiss origin" , "Kind of mountain cabin in Switzerland" , "Swiss hut or cottage" , "Swiss hut for mountaineers" .)
