Big plot of land for either partner advertised in the Farmers Journal perhaps (7)
I believe the answer is:
tractor
'big plot' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'of land for either partner advertised in the farmers journal perhaps' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'land' could be 'tract' (I've seen this in other clues) and 'tract' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tractor that I've seen before include "Farming vehicle" , "I can draw" , "Agricultural machine" , "Vehicle for pulling farm machinery" , "Powerful farm vehicle for heavy work" .)
