Recreation managed by doctor (1,3,1)
I believe the answer is:
r and r
'recreation' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?
'managed by doctor' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'by' is a charade indicator (letters next to each other).
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'ran'+'dr'='R AND R'
Can you help me to learn more?
(Other definitions for r and r that I've seen before include "relaxation" , "A break from continuous service" .)
