The term 'arrogant sort' can be defined by three words: SNOOT (5 letters), PRIG (4 letters), and SNOB (4 letters). SNOOT is a slang term for someone who is overly pretentious or snobbish. PRIG is an old-fashioned word for someone who is excessively prim and proper, often in a way that is seen as annoying or irritating. Finally, SNOB is a person who believes they are superior to others and looks down on them. All three words describe someone who is arrogant and haughty.
