Considered as belonging, a model had a go about objection (10)
I believe the answer is:
attributed
'considered' is the definition.
The definition and answer can be both related to thinking as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'belonging a model had a go about objection' is the wordplay.
'belonging a model' becomes 'at' (I can't justify this - if you can you should give a lot more credence to this answer).
'had a go' becomes 'tried' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'objection' becomes 'but' (as in 'no ifs, no buts').
'tried' going around 'but' is 'tributed'.
'at'+'tributed'='ATTRIBUTED'
'as' is the link.
Can you help me to learn more?
(Another definition for attributed that I've seen is " Ascribed".)
