Climbing a tree, could you hear it bend? (5)
I believe the answer is:
bough
'climbing' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'a tree could you hear it bend?' is the wordplay.
I cannot really understand how this works, but
'tree' could be 'bo' (bo tree is a kind of tree) and 'bo' is found within the answer.
'you' could be 'u' (commonly used in online communication) and 'u' is found 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 bough that I've seen before include "Main branch (of tree)" , "Substantial branch of a tree" .)
