'snobbish' originates from the English word 'snob', which was used in the 18th century to describe a shoemaker or cobbler, and later evolved to mean someone who imitates the manners of the upper class.

'snob' changed from its original meaning of 'shoemaker' to 'someone who imitates the upper class' in the 19th century, eventually leading to the adjective 'snobbish'.

Initially, it meant 'shoemaker', but over time it evolved into its current meaning of 'having an attitude of superiority'.
