Doctor put a tie on before initially treating casualty
I believe the answer is:
outpatient
'casualty' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'doctor put a tie on before initially treating' is the wordplay.
'doctor' is an anagram indicator.
'before' is a charade indicator (letters next to each other).
'initially' suggests taking the first letters.
The initial letter of 'treating' is 't'.
'put'+'a'+'tie'+'on'='putatieon'
'putatieon' anagrammed gives 'outpatien'.
'outpatien'+'t'='OUTPATIENT'
Can you help me to learn more?
(Other definitions for outpatient that I've seen before include "Hospital visitor" , "Person attending hospital" , "Non-resident hospital user" , "travelling case" , "one needs treatment" .)
