Only leaves what you deserve to get (4,7)
I believe the answer is:
just deserts
'you deserve to get' is the definition.
I can't tell whether this definition defines the answer.
'only leaves' is the wordplay.
'only' becomes 'just' (synonyms).
'leaves' becomes 'deserts' (to desert someone is to leave them).
'just'+'deserts'='JUST DESERTS'
'what' is the link.
Can you help me to learn more?
(Other definitions for just deserts that I've seen before include "What one has coming" , "Fair fate - rightful reward" , "Fate or results one deserves" .)
