Plan an area for cultivation (4)
I believe the answer is:
plot
'plan' is the definition.
(I know this)
'an area for cultivation' is the wordplay.
I cannot quite understand how this works, but
'area' could be 'lot' (lot is a kind of area) and 'lot' is found within the answer.
A single letter 'p' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for plot that I've seen before include "Conspiracy, secret plan" , "lost in poor judgment" , "A conspiracy or small piece of land" , "Area of ground; storyline" , "Vegetable garden - scheme" .)
