Glues pieces of wood (6)
I believe the answer is:
sticks
I believe this clue is a triple definition!
'glues' is the first definition.
(I've seen this before)
'pieces' is the second definition.
(stick is a kind of piece)
'of' is a link.
'wood' is the third definition.
(I've seen this before)
(Other definitions for sticks that I've seen before include "Stands" , "Is bogged down" , "Glues" , "bits of wood" , "Refuses to move" .)
