Bags the loud woodwind instrument (5)
I believe the answer is:
sacks
'bags' is the definition.
(I know this)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sacks that I've seen before include "Raids; boots out" , "Plunders; bags" , "Dismisses; bags" , "Terminates employment as punishment" , "Bags; wines" .)
