Introduced the editor now in office (9)
I believe the answer is:
presented
'introduced' is the definition.
('present' can be a synonym of 'introduce')
'editor now in office' is the wordplay.
I cannot quite understand how this works, but
'editor' could be 'ed' (abbreviation) and 'ed' is found in the answer.
'now' could be 'present' (the present time) and 'present' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for presented that I've seen before include "Gave formally or officially" , "Introduced, brought forward" , "Made a gift to" , "Given" , "Gave formally, award say" .)
