Indian in large house yard displays wickedness (8)
I believe the answer is:
villainy
'wickedness' is the definition.
(I've seen this before)
'indian in large house yard' is the wordplay.
'indian' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'large house' becomes 'villa' (I've seen this before).
'yard' becomes 'y' (abbreviation).
'villa'+'y'='villay'
'in' put inside 'villay' is 'VILLAINY'.
'displays' acts as a link.
Can you help me to learn more?
(Other definitions for villainy that I've seen before include "Wicked behaviour" , "foul play" , "Criminality" , "Vile behaviour, evil act" , "Wickedness" .)
