Having a baby but not coming out with the truth? (5-2)
I believe the answer is:
lying-in
'truth?' is the definition.
The definition and answer can be both states of affairs as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lying-in that I've seen before include "Confinement" , "Staying abed - confined in childbirth" .)
