Lecture; moral (6)
I believe the answer is:
lesson
I believe this is a double definition.
'lecture' is the first definition.
(I've seen this before)
'moral' is the second definition.
(synonyms)
(Other definitions for lesson that I've seen before include "Cautionary tale" , "See 1" , "School period" , "Sermon or class session" , "Portion of instruction" .)
