Confinement when stockpiling, having overlooked area (5-2)
I believe the answer is:
lying-in
'confinement' is the definition.
(I know that confinement can be written as lying-in)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for lying-in that I've seen before include "Staying abed - confined in childbirth" , "Confinement" .)
