Small woody shoot (4)
I believe the answer is:
twig
'small woody shoot' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for twig that I've seen before include "Small part of tree - suddenly understand" , "Small tree shoot" , "Part of a tree branch" , "Suddenly see; branchlet" , "A small branch - cop on?" .)
