Leaps in bed perhaps (7)
I believe the answer is:
springs
'leaps' is the definition.
(I know this)
'in bed perhaps' is the wordplay.
I cannot quite see how this works, but
'in' is within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for springs that I've seen before include "Natural flows of ground water" , "Jumps; metal coils" , "Elastic metal coils" , "what might be after Alice?" .)
