'interdependence' originates from the Latin word 'interdependere,' where 'inter-' meant 'between' and 'dependere' meant 'to hang down or rely.'

'interdependere' transformed into the French word 'interdépendance,' and eventually became the modern English word 'interdependence' through Middle English.

Initially, it meant 'to rely on each other,' and this meaning has largely remained the same in modern usage.
