'collapsible' originates from the Latin word 'collapsus,' where 'col-' meant 'together' and 'lapsus' meant 'to slip or fall.'

'collapsus' transformed into the French word 'collapsable,' and eventually became the modern English word 'collapsible.'

Initially, it meant 'to fall together,' but over time it evolved into its current meaning of 'capable of being folded or compressed.'
