Room for movement in Spooner's little song (6)
I believe the answer is:
leeway
'room for movement' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for leeway that I've seen before include "Slack" , "Room to manoeuvre, latitude" , "Allowable margin, latitude" , "Drift - scope for action" , "Elbow room?" .)
