'collider' originates from the English word 'collide,' which comes from the Latin word 'collidere,' where 'col-' meant 'together' and 'laedere' meant 'to strike.'

'collidere' transformed into the English word 'collide,' and eventually became the modern English word 'collider' through the addition of the suffix '-er' to denote an agent noun.

Initially, it meant 'to strike together,' but over time it evolved into its current meaning of 'a device that causes particles to collide.'
