Rustic got through said examination (8)
I believe the answer is:
pastoral
'rustic' is the definition.
(synonyms)
'through said examination' is the wordplay.
'through said' becomes 'past' (I can't explain this - if you can you should give a lot more credence to this answer).
'examination' becomes 'oral' (oral is a kind of examination).
'past'+'oral'='PASTORAL'
'got' acts as a link.
Can you help me to learn more?
(Other definitions for pastoral that I've seen before include "Portraying romanticised country life" , "To do with shepherds, or concerned with spiritual guidance" , "Letter to church members" , "Relating to the countryside or shepherds" , "of a priest" .)
