Stopped working and went to bed (7)
I believe the answer is:
retired
I believe this is a double definition.
'stopped working' is the first definition.
(I've seen this in another clue)
'went to bed' is the second definition.
('retire' can be a synonym of 'go to bed')
'and' acts as a link.
(Other definitions for retired that I've seen before include "retreated" , "No longer working" , "Stopped work - went to bed" , "out of office?" , "Turned in" .)
