'well-provided' originates from the combination of 'well' and 'provided', where 'well' meant 'in a good or satisfactory way' and 'provided' meant 'supplied or equipped'.

'well-provided' changed from the Old English word 'wel' and the Middle English word 'providen', eventually becoming the modern English word 'well-provided'.

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