Ever-changing journalist swerved (6)
I believe the answer is:
veered
'swerved' is the definition.
('veer' can be a synonym of 'swerve')
'ever-changing journalist' is the wordplay.
'changing' indicates an anagram.
'journalist' becomes 'ed' (short for editor).
'ever' is an anagram of 'veer'.
'veer'+'ed'='VEERED'
(Other definitions for veered that I've seen before include "Swerved" , "once let out at sea" , "Changed direction abruptly" , "Took evasive action" , "Changed direction or course, as wind may" .)
