B. Bryson riled about English snootiness (8)
I believe the answer is:
snobbery
'snootiness' is the definition.
(I've seen this in another clue)
'b bryson riled about english' is the wordplay.
'riled' is an anagram indicator (letters must be irritated or riled up).
'about' is an insertion indicator.
'english' becomes 'e' (abbreviation).
'b'+'bryson'='bbryson'
'bbryson' is an anagram of 'snobbry'.
'snobbry' going around 'e' is 'SNOBBERY'.
(Other definitions for snobbery that I've seen before include "Haughtiness" , "Quality of thinking others socially inferior" , "Condescension towards those with lower status" , "Superciliousness" , "Stuck-up attitude" .)
