'well-disposed' originates from the combination of 'well' and 'disposed,' where 'well' meant 'in a good manner' and 'disposed' meant 'inclined or having a tendency.'

'well-disposed' changed from the Middle English word 'disposen,' which meant 'to arrange or set in order,' and eventually became the modern English word 'disposed' with the prefix 'well' added to indicate a positive inclination.

Initially, it meant 'arranged in a good manner,' but over time it evolved into its current meaning of 'having a positive or friendly attitude.'
