Capsized because steered too sharply (10)
I believe the answer is:
overturned
'capsized' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for overturned that I've seen before include "Placed upside down" , "Capsized" , "Reversed (a legal decision)" .)
