Few who set out with a restorer peaked (3,5,3,4)
I believe the answer is:
the worse for wear
'peaked' is the definition.
I know nothing about this answer so I can't tell whether this works.
'few who set out with a restorer' is the wordplay.
'set out with' indicates anagramming the letters.
'few'+'who'='fewwho'
'a'+'restorer'='arestorer'
'fewwho' with its letters mixed up with 'arestorer' gives 'THE WORSE FOR WEAR'.
Can you help me to learn more?
(Other definitions for the worse for wear that I've seen before include "Tired and emotional" , "Drunk (colloq.)" , "Shabby; drunk" .)
