Misinformation returned? Don’t worry (3,4)
I believe the answer is:
lie back
'don't worry' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'misinformation returned?' is the wordplay.
'misinformation' becomes 'lie' (lies are false information).
'returned?' becomes 'back' (I've seen this in other clues).
'lie'+'back'='LIE BACK'
Can you help me to learn more?
(Other definitions for lie back that I've seen before include "Recline" , "lounge?" , "Relax" .)
