Rock-and-roll - or rest and recreation? (1,3,1)
I believe the answer is:
r and r
'recreation?' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for r and r that I've seen before include "A break from continuous service" , "relaxation" .)
