Rich, fit, and recovered from injury, say (4-6)
I believe the answer is:
well-heeled
'rich' is the definition.
(I've seen this before)
'fit and recovered from injury say' is the wordplay.
'fit' becomes 'well' ('well' is associated in meaning with 'fit'**).
'and' says to put letters next to each other.
'recovered from injury' becomes 'healed'.
'say' shows a homophone (sound like).
'healed' is a homophone of 'heeled'.
'well'+'heeled'='WELL HEELED'
(Other definitions for well-heeled that I've seen before include "Wealthy" , "Prosperous, rich" , "Affluent" , "Comfortably off" .)
