Adheres to kindling (6)
I believe the answer is:
sticks
This clue is a double definition.
'adheres' is the first definition.
('stick' can be a synonym of 'adhere')
'to kindling' is the second definition.
(I've seen this in another clue)
(Other definitions for sticks that I've seen before include "Old fogeys" , "basic furniture" , "bits of wood" , "Adheres" , "potentially breaking our bones?" .)
