Country expert perhaps involved in upcoming event Simon organised (10)
I believe the answer is:
agronomist
'country expert perhaps involved' is the definition.
I can't tell whether this defines the answer.
'in upcoming event simon organised' is the wordplay.
'upcoming' says the letters should be written backwards.
'in' indicates a hidden word.
'tsimonorga' is hidden within 'event simon organised'.
'tsimonorga' back-to-front is 'AGRONOMIST'.
Can you help me to learn more?
(Other definitions for agronomist that I've seen before include "Farming expert" , "Crop expert" , "occupation for expert on land" , "Crop specialist" .)
