A programme cameo reviewed (9)
I believe the answer is:
appraised
'reviewed' is the definition.
The answer and definition can be both related to thinking as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'a programme cameo' is the wordplay.
'a programme' becomes 'app' (type of computer programme).
'cameo' becomes 'raised' (I am not sure about this - if you are sure you should believe this answer much more).
'app'+'raised'='APPRAISED'
Can you help me to learn more?
(Other definitions for appraised that I've seen before include "Evaluated" , "Valued" , "Did judge" , "Disappear (anag)" .)
