Sleeping partner stimulating dry debate (5,4)
I believe the answer is:
teddy bear
'sleeping partner' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'stimulating dry debate' is the wordplay.
'dry debate' can be anagrammed to 'TEDDY BEAR'.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for teddy bear that I've seen before include "Cuddly ursine" , "Stuffed toy" , "Child's toy, musically in picnic" , "Popular cuddly toy" , "Cuddly toy named after a US president" .)
