Cry about northern elitist (4)
I believe the answer is:
snob
'elitist' is the definition.
(I've seen this before)
'cry about northern' is the wordplay.
'cry' becomes 'sob' (sobbing is a kind of crying).
'about' is an insertion indicator.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'sob' enclosing 'n' is 'SNOB'.
(Other definitions for snob that I've seen before include "Stuck-up person" , "One despising inferiors" , "blackleg" , "Looker-down on others" , "One looking down on others" .)
