House in wild glen collapsed (8)
I believe the answer is:
dwelling
'house' is the definition.
(somewhere people live)
'wild glen collapsed' is the wordplay.
'collapsed' is an anagram indicator.
'wild'+'glen'='wildglen'
'wildglen' is an anagram of 'DWELLING'.
'in' is the link.
(Other definitions for dwelling that I've seen before include "Home" , "Place of residence" , "house" , "Harping" , "Domicile" .)
