Hushaby baby supporter (5)
I believe the answer is:
bough
This could be a double definition.
'hushaby' is the first definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'baby supporter' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
Can you help me to learn more?
(Other definitions for bough that I've seen before include "Substantial branch of a tree" , "Main branch (of tree)" .)
