Destroys odd pieces (4)
I believe the answer is:
ends
This could be a double definition.
'destroys' is the first definition.
(I've seen this before)
'odd pieces' is the second definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for ends that I've seen before include "Justifications for means, sometimes?" , "Ceases, closes or dies" , "Desired results" , "'Goals, objectives (4)'" , "Odds and --" .)
