'projector' originates from Latin, specifically the word 'proicere,' where 'pro-' meant 'forward' and 'iacere' meant 'to throw.'

'proicere' transformed into the French word 'projecteur,' and eventually became the modern English word 'projector' through Middle English.

Initially, it meant 'to throw forward,' but over time it evolved into its current meaning of 'a device that projects images or videos.'
