Turned sharply (6)
I believe the answer is:
veered
'turned sharply' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for veered that I've seen before include "Tacked suddenly" , "Changed direction abruptly" , "Took evasive action" , "once let out at sea" , "Swerved" .)
