Take a risk, as a tree surgeon might? (2,3,2,1,4)
I believe the answer is:
go out on a limb
'take a risk' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for go out on a limb that I've seen before include "Take a risk" , "Be brave (2,3,2,1,4)" , "become isolated" .)
