Rosie, extremely weary, stopped working (7)
I believe the answer is:
retired
'stopped working' is the definition.
(I've seen this in another clue)
'rosie extremely weary' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'weary' becomes 'tired' (similar in meaning).
'rosie' with its centre removed is 're'.
're'+'tired'='RETIRED'
(Other definitions for retired that I've seen before include "Gone to bed" , "Withdrew from active participation" , "Ceased working" , "No longer working" , "Left" .)
