Clean home wrecked for changeable type (9)
I believe the answer is:
chameleon
'for changeable type' is the definition.
(chameleon can mean a changeable person)
'clean home wrecked' is the wordplay.
'wrecked' is an anagram indicator.
'clean'+'home'='cleanhome'
'cleanhome' is an anagram of 'CHAMELEON'.
(Other definitions for chameleon that I've seen before include "fickle person" , "Lizard whose skin changes colour" , "colour changer" , "Small lizard able to change colour" , "Person who keeps changing" .)
