Doctor gets you improving finally -- prescribing this? (4)
I believe the answer is:
drug
'prescribing this?' is the definition.
The definition suggests a singular noun which matches the answer.
'doctor gets you improving finally' is the wordplay.
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor'**).
'gets' says to put letters next to each other.
'finally' says to take the final letters.
The last letters of 'you improving' are 'ug'.
'dr'+'ug'='DRUG'
Can you help me to learn more?
(Other definitions for drug that I've seen before include "Substance used as medicine or narcotic" , "Chemical medicament" , "Sedate" , "Perhaps grass" , "Pharmaceutical (or recreational) item" .)
