'interact' originates from Latin, specifically the word 'interactus,' where 'inter-' meant 'between' and 'actus' meant 'act.'

'interactus' transformed into the French word 'interagir,' and eventually became the modern English word 'interact' through Middle English.

Initially, it meant 'to act between,' but over time it evolved into its current meaning of 'to act reciprocally or communicate.'
