Cooper finally cuts trees to make parts of barrels (8)
I believe the answer is:
breeches
'barrels' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for breeches that I've seen before include "Pants" , "Trousers reaching to just below the knee" , "Short trousers" , "Trousers worn with stockings" , "Riding trousers" .)
