It may be hatched (4)
I believe the answer is:
plot
'it may be hatched' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for plot that I've seen before include "Small area of ground" , "Scheme or small piece of land" , "Chart - area" , "Scheme, story and piece of ground" , "... of story, family ..." .)
