A stretcher to boot (4)
I believe the answer is:
tree
This clue could be a double definition.
'a stretcher' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'boot' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for tree that I've seen before include "Large shrub; family line" , "Eg, laburnum" , "Elm, perhaps" , "Oak, for example" , "Hazel for instance" .)
