Commotion in field (5)
I believe the answer is:
scene
'commotion' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for scene that I've seen before include "Subdivision of act in play" , "Part of a 16" , "Part of Hamlet" , "Vista or stage setting" , "Part of a pantomime" .)
