Changeable type in unusually clean home (9)
I believe the answer is:
chameleon
'changeable type' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'unusually clean home' is the wordplay.
'unusually' indicates anagramming the letters.
'clean'+'home'='cleanhome'
'cleanhome' with letters rearranged gives 'CHAMELEON'.
'in' is the link.
Can you help me to learn more?
(Other definitions for chameleon that I've seen before include "It blends" , "One to blend in" , "colour changer" , "Lizard able to change its skin colour" , "Lizard hard to spot" .)
