Stop to get wood (5)
I believe the answer is:
brake
'stop' is the definition.
(braking is a kind of stopping)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for brake that I've seen before include "Decelerate" , "Horse-drawn carriage" , "Device to slow down a vehicle" , "Device for slowing or stopping car" , "Constraint" .)
