Given a rest, medicinally (7)
I believe the answer is:
sedated
'given' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sedated that I've seen before include "Drugged" , "Given calming drugs" , "Under the influence of drugs" , "Dead set (anag) - tranquillised" , "Calmed with drugs" .)
