Team’s diet needs shaking up, it’s thought (9)
I believe the answer is:
estimated
'thought' is the definition.
The definition and answer can be both related to thinking as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'team's diet needs shaking up' is the wordplay.
'team's diet' can be anagrammed to 'ESTIMATED'.
Though, I'm not clear how this is indicated.
'it's' is the link.
Can you help me to learn more?
(Other definitions for estimated that I've seen before include "Rough" , "Worked out" , "Calculated roughly" , "Calculated approximately" , "Judged roughly" .)
