'consumerism' originates from the word 'consumer,' which comes from the Latin word 'consumere,' meaning 'to use up or eat.'

'consumer' evolved from the Latin 'consumere' through Old French 'consumer,' eventually becoming the modern English word 'consumer.'

Initially, it meant 'to use up or eat,' but over time it evolved into its current meaning of 'the protection or promotion of the interests of consumers.'
