A snob, perhaps, where title is involved? (7)
I believe the answer is:
elitist
'a snob' is the definition.
(I've seen this in another clue)
'where title is involved?' is the wordplay.
'where' is an anagram indicator (I've seen this in other clues).
'involved?' means one lot of letters goes inside another.
'title' anagrammed gives 'elitt'.
'elitt' enclosing 'is' is 'ELITIST'.
'perhaps' is the link.
(Other definitions for elitist that I've seen before include "(One who is) discriminating in favour of select few" , "One without the common touch" , "arrogant" , "One who feels superior" , "Looking down on others" .)
