Put out of office, editor upset over attitude (6)
I believe the answer is:
depose
'put out' is the definition.
(I've seen this in another clue)
'editor upset over attitude' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'upset over' is a reversal indicator (knocked over).
'attitude' becomes 'pose' (attitude can mean a pose or stance).
'ed' in reverse letter order is 'de'.
'de'+'pose'='DEPOSE'
'of office' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for depose that I've seen before include "Remove from top position" , "Force out of office" , "Oust or unseat" , "Remove (from high office)" , "Set down" .)
