'well-resourced' originates from the combination of 'well' and 'resource,' where 'well' meant 'in a good or satisfactory way' and 'resource' referred to 'a stock or supply of materials.'

'well-resourced' evolved from the Middle English word 'resourcen,' which meant 'to provide with resources,' and eventually became the modern English term 'well-resourced.'

Initially, it meant 'adequately supplied with resources,' and this meaning has largely remained the same in modern usage.
