Stick from tree (3)
I believe the answer is:
gum
I believe this clue is a double definition.
'stick' is the first definition.
(gum can mean to glue or stick)
'tree' is the second definition.
(I know that gum is a type of tree)
'from' acts as a link.
(Other definitions for gum that I've seen before include "To stick with adhesive" , "Sticky stuff - tree" , "seal" , "Chewy stuff, hard to clean away" , "Leaving body" .)
