'snob' originates from the Latin word 'sine nobilitate', meaning 'without nobility'.

'sine nobilitate' transformed into the English word 'snob', initially used to describe a shoemaker or a common person, and eventually became the modern English word 'snob' with its current meaning.

Initially, it meant 'a common person or shoemaker', but over time it evolved into its current meaning of 'a person who believes they are superior to others'.
