'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 'one who plans or devises,' but over time it evolved into its current meaning of 'a device that projects images.'
