Instructive talk and reprimand (7)
I believe the answer is:
lecture
I believe this clue is a double definition.
'instructive talk' is the first definition.
(I've seen this before)
'reprimand' is the second definition.
(I know that reprimand can be written as lecture)
'and' acts as a link.
(Other definitions for lecture that I've seen before include "Class at university" , "Discourse for students" , "Oral discourse on a subject" , "Teaching discourse" , "Deliver a talk" .)
