Does wrong to open a shop for medicinal treatment (5)
I believe the answer is:
doses
'for medicinal treatment' is the definition.
I can't judge whether this defines the answer.
'does wrong to open a shop' is the wordplay.
'wrong' is an anagram indicator.
'to open' says to take the initial letters (take the opening letter).
The initial letter of 'shop' is 's'.
'does' with letters rearranged gives 'dose'.
'dose'+'s'='DOSES'
Can you help me to learn more?
(Other definitions for doses that I've seen before include "Gives medicine to" , "Prescribed amounts of medication" , "Potion portions" , "Prescribed quantities of medicine" , "Measured portions of medicine" .)
