Owned headnote, literally (3)
I believe the answer is:
had
'owned' is the definition.
('have' can be a synonym of 'own')
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for had that I've seen before include "Possessed; cheated" , "Taken in" , "Was bound to be - caught" , "Was in possession of" , "Did trick" .)
