Titles, I suspect, will reveal a snob? (7)
I believe the answer is:
elitist
'a snob?' is the definition.
(thesaurus)
'titles i suspect' is the wordplay.
'suspect' is an anagram indicator.
'titles'+'i'='titlesi'
'titlesi' is an anagram of 'ELITIST'.
'will reveal' acts as a link.
(Other definitions for elitist that I've seen before include "Member of a self-regarding group" , "Narrowly superior" , "One showing superior attitude" , "Favouring exclusivity" , "One who treats certain people as superior group" .)
