'single-format' originates from the combination of 'single,' meaning 'one' or 'individual,' and 'format,' which comes from the Latin 'formatus,' meaning 'to shape or form.'

'format' changed from the Latin word 'formatus' and eventually became the modern English word 'format.'

Initially, 'format' meant 'to shape or form,' but over time it evolved into its current meaning of 'a specific arrangement or layout.'
