There's a point in the question raised by a farmer (5)
I believe the answer is:
wheat
'raised by a farmer' is the definition.
I can't tell whether this defines the answer.
'there's a point in the question' is the wordplay.
'there's a point' becomes 'e' (compass point).
'in' is an insertion indicator.
'the question' becomes 'what' (what is a question word).
'e' placed inside 'what' is 'WHEAT'.
Can you help me to learn more?
(Other definitions for wheat that I've seen before include "Cereal for bread/pasta" , "Source of flour" , "Bread ingredient" , "Cereal grass" , "Cereal grain" .)
