Building seen from both ends of the editor's office (7)
I believe the answer is:
edifice
'building' is the definition.
(synonyms)
'both ends of the editor's office' is the wordplay.
I cannot really see how this works, but
'editor' could be 'ed' (abbreviation) and 'ed' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'seen from' acts as a link.
Can you help me to learn more?
(Other definitions for edifice that I've seen before include "Large structure" , "Impressive building" , "impressive pile!" , "Grand building" , "Monument" .)
