'resource-dependent' originates from the combination of 'resource' and 'dependent', where 'resource' refers to a stock or supply of materials and 'dependent' means relying on something else for support.

'resource' comes from the Old French word 'resourse', and 'dependent' comes from the Latin word 'dependere', meaning 'to hang down from'.

Initially, 'dependent' meant 'hanging down from', but over time it evolved to mean 'relying on something else'.
