Little affront (6)
I believe the answer is:
slight
I believe this clue is a double definition.
'little' is the first definition.
('slight' can be similar in meaning to 'little')
'affront' is the second definition.
(I've seen this before)
(Other definitions for slight that I've seen before include "A disrespectful reference - not great" , "Minor -- snub" , "of no great significance" , "Insignificant, flimsy" , "Minor - insult" .)
