Directors and editor got on (7)
I believe the answer is:
boarded
'got on' is the definition.
('board' can be a synonym of 'get on')
'directors and editor' is the wordplay.
'directors' becomes 'board' (board of directors).
'and' means one lot of letters go next to another.
'editor' becomes 'ed' (abbreviation).
'board'+'ed'='BOARDED'
(Other definitions for boarded that I've seen before include "Embarked" , "Got on (a ship)" .)
