'classless' originates from the English word 'class' combined with the suffix '-less,' where 'class' meant 'a group of people with similar social or economic status' and '-less' meant 'without.'

'class' transformed from the Latin word 'classis,' and eventually became the modern English word 'class' through Old French.

Initially, it meant 'without a class or category,' but over time it evolved into its current meaning of 'lacking social or economic class distinctions.'
