Empire that's been stuffed (7)
I believe the answer is:
ottoman
'empire' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ottoman that I've seen before include "Couch for a Turk" , "Turkish empire or ling cushioned seat" , "that lacks arms and backing" , "Turkish empire of over 600 years" , "Long, low seat - Turkish" .)
