The term 'superior sort' can be defined by two crossword solutions: SNOB (4 letters) and EGOIST (6 letters). A SNOB is someone who believes they are superior to others and looks down on those who do not have the same social status or wealth. An egoist is someone who is excessively self-centered and only cares about their own interests and desires. Both terms imply a sense of superiority and selfishness.
