Not develop much scorn (8)
I believe the answer is:
belittle
'scorn' is the definition.
I cannot understand how the remainder of the clue works.
(Other definitions for belittle that I've seen before include "abuse" , "Imply that person is inferior" , "Imply that something is of small value, diminish in words" , "Make to seem unimportant" , "Imply that person or thing is unimportant" .)
