Medic describing their patients is a bore (5)
I believe the answer is:
drill
'a bore' is the definition.
(bore can mean to drill into something)
'medic describing their patients' is the wordplay.
I cannot really see how this works, but
'medic' could be 'dr' (doctor) and 'dr' is located in the answer.
The remaining letters 'ill' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for drill that I've seen before include "Monkey" , "it could get boring" , "Exercise or teach through repeated practice" , "Exercise by repeated practice - bore" , "Stout cotton cloth" .)
