Doctor can misread official agreement (9)
I believe the answer is:
concordat
'official agreement' is the definition.
'concordat' can be an answer for 'agreement' (concordat is a kind of agreement). I am unsure of the 'official' bit.
'doctor can misread' is the wordplay.
'misread' indicates an anagram.
'doctor'+'can'='doctorcan'
'doctorcan' is an anagram of 'CONCORDAT'.
Can you help me to learn more?
(Other definitions for concordat that I've seen before include "Signed agreement" , "papal blessing" , "Agreement with Rome" , "pact" .)
