Retire from hospital? Dismissal following appeal (3,3,4)
I believe the answer is:
hit the sack
'retire' is the definition.
(synonyms)
'hospital? dismissal following appeal' is the wordplay.
'hospital?' becomes 'h' (abbreviation for hospital on maps).
'dismissal' becomes 'thesack' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'following' says to put letters next to each other.
'appeal' becomes 'it' ('it' can mean something attractive or appealing).
'thesack' put after 'it' is 'itthesack'.
'h'+'itthesack'='HIT THE SACK'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for hit the sack that I've seen before include "Retired" , "Go to bed" , "went to bed" , "retire" , "Drank a lot of vintage wine" .)
