Became weary again and withdrew (7)
I believe the answer is:
retired
'withdrew' is the definition.
('retire' can be a synonym of 'withdraw')
'became weary again' is the wordplay.
I cannot quite see how this works, but
'weary' could be 'retire' (retiring is a kind of wearying) and 'retire' is located in the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for retired that I've seen before include "Stopped working" , "No longer working" , "Turned in" , "Gave up job, relaxed on pension" , "Ceased working" .)
