Get small branch (4)
I believe the answer is:
twig
I believe this is a double definition.
'get' is the first definition.
(thesaurus)
'small branch' is the second definition.
(I've seen this before)
(Other definitions for twig that I've seen before include "Part of a tree branch" , "Finally understand" , "Slender woody shoot" , "A small branch - geddit?" , "Small piece of tree" .)
