Posing on purpose for dupe (7,6)
I believe the answer is:
sitting target
'dupe' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'posing on purpose' is the wordplay.
'posing on' becomes 'sitting' (sitting is a kind of posing. I am not sure about the 'on' bit.**).
'purpose' becomes 'target' (I've seen this before).
'sitting'+'target'='SITTING TARGET'
'for' is the link.
Can you help me to learn more?
(Other definitions for sitting target that I've seen before include "Aunt Sally, perhaps" , "Easy victim" , "Vulnerable person" , "Something easy to hit" .)
