Ask about urns, accommodating several changes of mind (1-5)
I believe the answer is:
u-turns
'changes of mind' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for u-turns that I've seen before include "Complete reversals, of direction or opinion" , "Complete reverses, cars or attitudes" , "Complete reversals of direction in car driving" , "Complete reversals, cars or decisions" , "Complete reversals, of cars or attitudes" .)
