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

'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 communicate or engage with someone or something.'
