Plan to shoot round the corner (4)
I believe the answer is:
plot
'plan' is the definition.
(plotting is a kind of planning)
'shoot round the corner' is the wordplay.
'shoot' becomes 'pot' (I've seen this in other clues).
'round' indicates putting letters inside.
'the corner' becomes 'l' (I can't explain this - if you can you should give a lot more credence to this answer).
'pot' enclosing 'l' is 'PLOT'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for plot that I've seen before include "Graph; piece of ground" , "Piece of land or cunning scheme" , "Conspire - small piece of land" , "Scheme; graph" , "Novel story - secret plan" .)
