Doctor introducing brief order into practice (6)
I believe the answer is:
medico
'practice' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'doctor introducing brief order' is the wordplay.
'doctor' becomes 'medic' (I've seen this before**).
'introducing' means one lot of letters go next to another.
'brief' means to remove the last letter.
'order' becomes 'om' (order of merit).
'om' with its last letter taken away is 'o'.
'medic'+'o'='MEDICO'
'into' is the link.
Can you help me to learn more?
(Other definitions for medico that I've seen before include "Doctor" , "quack" , "Health practitioner" .)
