Disinclined to have acted as a model after work (7)
I believe the answer is:
opposed
'disinclined' is the definition.
('opposed' can be similar in meaning to 'disinclined')
'model after work' is the wordplay.
'model' becomes 'posed' (I can't justify this - if you can you should believe this answer much more).
'after' means one lot of letters go next to another.
'work' becomes 'op' (abbreviation for opus).
'posed' put after 'op' is 'OPPOSED'.
'to have acted as a' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for opposed that I've seen before include "likely to refuse?" , "like foes" , "Took contrary position to" , "Withstood" , "Stood against" .)
