Made logical judgements about a boy, Edward (8)
I believe the answer is:
reasoned
'made logical judgements' is the definition.
The definition and answer can be both related to thinking as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
'about a boy edward' is the wordplay.
'about' becomes 'rea' (I've seen this in other clues).
'a boy' becomes 'son' ('son' can be a synonym of 'boy').
'edward' becomes 'ed'.
'rea'+'son'+'ed'='REASONED'
Can you help me to learn more?
(Other definitions for reasoned that I've seen before include "made a logical case" , "Logically derived" , "Debated in calm and logical way" , "Well thought out" , "Logically valid" .)
