Lecturing in film, collecting exam paper with average grade (10)
I believe the answer is:
moralistic
'average grade' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I don't see?
'lecturing in film collecting exam paper' is the wordplay.
I cannot quite understand how this works, but
'film' could be 'm' (1931 Fritz Lang film) and 'm' is present in the answer.
'exam' could be 'oral' (spoken academic test) and 'oral' is found in the answer.
'paper' could be 'i' (the i is a UK newspaper) and 'i' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for moralistic that I've seen before include "Pronouncing on issues of right and wrong" , "Preachy" .)
