My patient will get better with treatment to hand (8)
I believe the answer is:
manicure
'my patient will' is the definition.
I can't tell whether this defines the answer.
'better with treatment to hand' is the wordplay.
'better with' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'treatment' becomes 'cure' (medical treatment).
'to' means one lot of letters go next to another (I've seen this in other clues).
'hand' becomes 'man' (both can mean a worker).
'i'+'cure'='icure'
'icure' put after 'man' is 'MANICURE'.
'get' acts as a link.
Can you help me to learn more?
(Other definitions for manicure that I've seen before include "Hand and nail treatment" , "Professional care for the hands" , "A numeric approach to care of the hands" , "Care of hands and nails" , "Grooming for 10, 17 and 18" .)
